Title: hypereagle's AMC V8 Mounting Kits
Post by: IowaEagle on May 30, 2009, 07:38:52 PM
Here are the pictures Terry recently sent me.   Hopefully he can provide some text to go along with them.  Few free to ask him questions within this thread.  These are "clicky pics" click on them to enlarge.

  It is the Eagle X member. The original mounts have to be cut off and mine welded in place of the old.

Terry thanks for the talk. Sounds interesting, like I said, you may get a call from me one of these days. Think I'm going to go talk to the dealer today & see what they think about trading for my car & giving me some cash to go with it.

Do you offering the motor mount kits for sale? If so, how much?
I can see that there will be a fair amount of cutting required. Do you have a set of detailed instructions to go along with it?

My brother and I just picked up an '81 SX/4 and are going to turn it into a rally car.  He's interested in keeping it all AMC.  I'm interested in more than 82hp.  I was hoping to get an idea on price so that I can pitch the idea of a 360ci/T5/119tc to him.  I believe that's pretty close to what you're running isn't it?
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on March 24, 2010, 06:34:41 PM
  $350.00 Cdn. The only cutting involved is the original frame mounts. Mounting the new ones can be tedious as clearances are tight all around. Making sure the bell housing is centered and low enough for the bolts to be put in and taken out.

if it is a 2 wheel drive then it is a spirit and WAY WAY rare.  I'd just keep it as close to stock as possible and look for an eagle to install a V8 in 
Title: Re: hypereagle's AMC V8 Mounting Kits

 You have either a Gremlin or a Kammback without a front diff. What would you like to know about the mounts?
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: 68AMXGOPAC on April 10, 2011, 10:06:13 AM
I have a question ,Hypereagle. Ok, maybe 2 : ) . If someone had no front diff in thier eagle, would a complete V8 crossmember from say a V8 spirit etc. fit right in ? and what color is your 73 Jav/Amx ? I had a plum crazy colored one, bone stock, 304 3spd. , even with the radio delete....lots of floor rot though.I paid $50 for it for the spoiler and fell in love with it and repaired it over a couple of years, my first AMC.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: IowaEagle on April 10, 2011, 06:31:14 PM
A Gremlin or Spirit would need the V8 cross member from another small bodied AMC (Hornet/Gremlin/Concord/AMC Spirit) and of course all of the correct mounting hardware.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: AMCKen on April 10, 2011, 11:44:13 PM
At a glance, I'd say the small car crossmember is the same whether V8 or 6. It's the brackets that are welded to it that are different. At a glance.
I'd put the 2 side by side and the brackets were the only difference I noted, but I didn't do any actual measuring to confirm.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: 68AMXGOPAC on April 11, 2011, 05:02:55 PM
Thanks guys. So it would seem maybe the mounting kit is the way to go , and have all the parts that way.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on April 13, 2011, 10:03:22 PM
The 2WD and 4WD cross members are way different from each other. The crossmember in the 4WD is what makes it the 4WD.It probably weighs 3 times that of the 2WD. It sweeps further ahead so the front diff sits behind it. this way the axles are also straight across from each other. As well you will notice that the lower control arms are 3 - 4 inches lower than the 2WD. The lower control arms are quite a bit different as they actually sweep rearwards as the 2WD go straight sieways. The most real noticable item a first sight is just how much taller the steering knuckle is on the 4WD.
 Ken is right all the small body cross members will bolt on anyone or the other. The difference from the 6 and 8 cyl  is just the brackets welded onto the crossmember which dictates whether 6 or 8 on the 2WD.
Never was a V8 cross member in 4WD and can't be done with the 2WD cross member.
Oh Ken I am parting out the 77AMX call me if you need something.

As well the 73 AMX which I no longer have was Bittersweet orange.  Now have a 70 AMX 390 4sd. Originally Bittersweet orange with Shadow mask.

I'm looking at the bell housing on the stcok tranny and wondering if the flywheels and flexplates will match up to the 360.

Pat sent me the "write up" on the 360 and even after downloading 3 different programs, I still cannot open the dang file. I tried calling Terry, but no response yet. No response to email either. I'm trying to pull off another one of those famous "Mav Miracles"... but need info ASAP. Anyone wanna chime in?

Just trying to figure up costs atm for what Pat needs in his. Luckily, he's got all the brackets needed and HyperEagle's custom mounts as well... but just curious what else is needed for the swap. Am I to assume that everything bolts up from there? It looks like there might be some "fun" with the stearing box... and since I planned on dropping my 360 in my Sx4, I'm curious how that will bolt up to the manual tranny with the clutch assembly and all that jazz.

The more info I get as fast as possible... the better my chances are on putting a smile on an ol'man's face! *wink*
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: mudkicker715 on September 04, 2011, 05:09:35 PM
Yes it will work. I have a 4.0l jeep tranny and flywheel behind my v8.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: Mavericke on September 04, 2011, 05:17:46 PM
So just to clarify... the 360 will bolt up to my original 4-speed tranny?
And the other 360 will bold up to it's original automatic tranny?
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on September 06, 2011, 08:23:01 PM
No problem with the bolting up where you have a problem is if you use the 6 cyl flywheel or flex plate. Less a 290 flywheel you will have an out balance engine and you will have a very noticeable vibration. Need the flywheel for the displacement of engine. Each AMC V8 displacement is balanced more or less than the next.
 360 for 360 401 for 401 etc. Can use the 6 cyl. flywheel if balanced for the correct V8 displacement.
I balanced my 6cyl. flywheel for a 360.
  Also be especially causess about year of engine when using an automatic trans. 1973- 1974 the torqueflite trans had the crank flange shape changed. You will those years to date engines. The earlier will not work unless the flange is machined and cchanged to except the later design torque convertor.
  Hope i didn't make it to complicated. My definitions may be hard to understand. If not quite sure please do call me as it would be easy for me to expllain over the phone if any extra questions need be asked.
  Thanks again  Terry   1-780-464-4907

Ok, so I guess I'm not sure what I do to correct the problem. Everything does seem to bolt up fine, we tested it out yesterday. So as far as the flywheel goes - I do intend to use the one from the I6... and it's all fairly new too... you saying I can take it in to have it machined for a 360? What am I supposed to tell these guys at the machine shop and how will though how to machine it properly to fit a 360?

And if I don't do it... how bad will the vibration be? Like, "omg, I can't drive this thing" bad... or like, "yeah, it vibrates a lil bit but you get used to it... who care, it's a V8 baby!".
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: Mavericke on September 07, 2011, 03:43:38 PM

The write up says you need an oil pan from a passenger car... so does anyone know what passenger cars qualify? Where should I be looking for find one... going to need the oil pan and the pickup.

I'll tell ya what I need... I need someone to say... "hey, you need an oil pan from *insert model/year here* and then you will be good to go for your 360 swap."

Anyone have a clue?
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on September 07, 2011, 07:32:54 PM
To be more specific about machine shop it should be an engine machine shop. The flywheel will nee to balanced for a 360 AMC. I could find out the proper weight for it. I do highly recomend not to run a 6 cyl. flywheel other wise as it will eventually take out main bearings starting with the rear one. It's not a cool vibration either as i have seen the wrong flywheels in AMC V8's in the past.
Title: Re: hypereagle's AMC V8 Mounting Kits

Hypereagle how do you know what is what? I'm asking on a manual.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: Mavericke on September 07, 2011, 09:04:52 PM
Hypereagle... can you please give me the specs I need for the I6 Manual Flywheel to be machine for the 80's Wagoneer 360? If you could give me whatever I need for the machine shop - that would be awesome. And you gotta spell it out like I'm a 3yr old too because I don't know anything about it, LOL! So please don't assume I know the lingo when you give me the specs. Give me exactly what I need to tell the machine shop.

What is needed to the automatic? I am trying to get Pat's ready as well but his is an automatic. So any specs or whatever else is needed would be helpful! Thanks!
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on September 09, 2011, 04:04:36 PM
I'll send some pics of what I did for my flywheel and talk to an AMCA member that did at one time have the proper flywheel/flexplate weight weight numbers.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: Mavericke on September 09, 2011, 05:18:20 PM
That'd be great guys! The good news is that I found a couple oil pans for Pat and I... knocked me back a few bucks, but will save some work in the long run.
Title: Re: hypereagle's AMC V8 Mounting Kits

Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: Mavericke on September 15, 2011, 12:08:43 PM
Sounds good... so it seems there is alot more parts involved in a 360 swap than just a 360, lol! Ugh, it's been nuts just trying to find everything needed.

I've learned that the 304 and 360 flexplates are so close (down to the tiniest fraction) in balancing that they will work for each other. I've also learned that you can take the flywheel off an automatic with the correct 360 balancing and have you 258 Flexplate balanced to those specks. You just take them both into the machine shop and tell them that you want the flexplate balanced the same as the flywheel and all will be done. This is also much cheaper than buying a new flexplate.

And as mentioned before, you need a smaller oil pan. Not just any Jeep 360 is going to work, you need to get an oil pan off of a passenger car. Luckily, in my search for information... I've found a NICE AMC bone yard that doesn't crush, only 25 miles from me. Not many Eagles left, but plenty AMC 304's and 360's from Ramblers and Javelins. Lots of those cars intact laying around there. I didn't have time to snag photos but I will be heading out there again soon to check everything out and maybe post some parts for anyone interested.

So yeah, even with a good running 360 and a solid Eagle... it's no simple task installing a 360. You're much better off digging one out from a passenger car in the first place.

I didn't use his mounts rather my own made and fabbed from what I have. Motor sits high in the bay but it needed basically nothing to go in there cept my fabricating.

You just take them both into the machine shop and tell them that you want the flexplate balanced the same as the flywheel and all will be done. This is also much cheaper than buying a new flexplate.

I think that is called "match balancing".  I read about a guy that made a fixture for match balancing flywheels on a Diesel 'Benz.  From what I understand, balancing is done one of two ways.  1- the entire rotating assembly (crank, flywheel/flexplate, harmonic balancer) is balanced as a unit, and 2- each piece is balanced separately.  If I understand it correctly, match balancing will only work for the first option (new flywheel is matched to the old, so the rest of the parts do not know a part has changed).  If all the parts are balanced separately, then all that needs to be done is have the new part balanced.  You will not be able to use option 1 unless you are tearing down the engine, so match balancing would be the only way to balance a replacement flywheel.   Someone please feel free to correct me if I am wrong.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: Mavericke on September 17, 2011, 02:07:12 AM
I think you're right Rich. The 360 is also balanced on the outside... can't remember the correct terminology for that but it basically means that it can be balanced separately from the crank and stuff. You're right too, it's called "match balancing".

I found most of the info on a Jeep site, but thought it would be useful here. Since the flywheel in my 258 is practically brand new (replaced with new clutch and all that jazz a couple years ago with practially no miles on them) then I will just have that flywheel match-balanced. I think it's the cheapest way to go.

AutoZone used to offer a remanned flywheel for $60 (with $80 core) but now only offer new ones for the 304/360 and they're $200!! Ouch! Can't swing that! I called a couple other places and one can't get them and the other is almost $300. Online is even worse. If anyone has any better ideas... please share!

I would love to be able to hand someone a 4.0 flywheel and a AMC V8 flywheel and get back a the 4.0 flywheel balanced properly to live behind a V8. There is a quarter inch difference between them and I've always been worried about having trouble with the clutch linkage. Do we know for sure that is easy to do?

Has anyone successfully put a 4.0 transmission behind an AMC V8 with the thicker flywheel? The hydraulic clutch cylinders might not care about the difference in thickness, but I don't want to assemble the cars on a guess. I have two pairs of Terry's Eagle V8 mounts I'm now gearing up to install.

I have two NV3550 5 speeds and one NSG370 6 speed from 2004 and 2006 Jeep Wranglers I want to put behind a 360 and a 401. I also have an AX15 with internal clutch cylinder that would be an option with the right flywheel. Right now I have an Advanced Adaptor that mates the NV3550 to a T5 bellhousing in order to retain all of the original flywheel thickness and clutch parts. That is not an option for the 6 speed because it has an intergral bellhousing.

Well, I'm not sure of the numbers on my tranny but it's the stock 4-speed manual they put in the SX4 in 1982. I just had the flexplate machined and balanced and it will be going on hopefully this weekend. I will let you know how it goes!
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on September 22, 2011, 11:46:01 PM
Used the 258 flywheel myself and balanced it for the 360. The nice part about the 6 cyl flywheel is that it's a lot lighter. Sort of like a V8 flywheel with the back side hollowed out if that makes any sense.

I will also need to machine and balance mine. Did you need a V8 flexplate or flywheel to compare to? Did you give the machine shop any figures or specifications?

Your four speed is called a SR4. It has reverse down and to the left of first. The T4 was available in later years, that has reverse back and to the right of third like the T5. A Jeep or Eagle T5 is a direct replacement and they can be found for a hundred dollars or so. The T5 is a very weak transmission and the SR4 is even weaker.

The SR4 belongs in the scrap heap. The fork on the shift lever has a deep notch on one side and it will eventually break. I've personally broken six of them. I have had to drive the car with a huge screwdriver in the top of the trans case multiple times. In contrast the T4 and T5 have a ball at the bottom that will not leave you stuck on the side of the road. Don't bother putting that junk back in such a nicely restored vehicle.

I had never heard of oil pan differences before. Do you have any comparison pictures? Do we know what vehicle donors definately work and which definately don't? I contacted a Javelin parts guy who said he had "late model" pans available, but I'm not exactly sure what that means.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on September 23, 2011, 08:54:23 PM
you know the possibility of my makeing this oil pan issue worse than it probably is I had seen a pic of an AMC V8 oil pan that I had never seen before or at least that I forgot about. The reason I have been saying use a car oil pan is the pic I saw  would most definately work in any AMC prodution car as the sump reached way far ahead. This would not clear any cars crossmember.
 Just search for an hour and could not find that pic. Any car should work.
 I too have no idea about what was said about early our later model pans either. The only differeance I know of and is insignificant is location of drain plug. Some on the side and some at the rear.

What I do remember is the pic of that oil pan was listed by 1 of the solid axle guys in the forum. Maybe some one will take note of this post and help us out.

Terry from the AMCA told me you did those mounts.  That's the first thing he said when I told him I was looking into doing a stroker motor - He goes "Nahhh, you need a 360 in that - get ahold of Hypereagle."
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: Mavericke on September 24, 2011, 12:15:22 AM
Yeah, those mounts are the way to go. Theoretically, you could fab as you went and save some cash but Hyper's brackets do make the job much easier.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: captspillane on September 24, 2011, 02:06:41 AM
It would take me over a week of measuring, comparing, grunting, and several prototypes before making a bracket as nice as his are. His brackets are an incredible value for how much time it takes to develop them yourself. Time is more precious than money to most of us. I definately agree that buying his brackets was the way to go.

There is a high capacity oil pan that is a common upgrade for Jeeps. The bottom of it is obviously larger and could only fit in a Jeep. I wonder if that was the picture you saw? The AMX/ Javelin guy I talked to said that his oil pans were used in both Jeeps and Passenger cars. I have a 304 from a CJ7 that I'm using to position the brackets and exhaust with. It will be replaced by a 401 once I buy one. I'll have to flip it upside down and bolt the axle to it and get back to you guys about whether a Jeep oil pan actually works or not.

I've removed the inapropriate posts and sent PM's to each of you directly regarding the matter. It can be dealt with in private instead of an an open forum where your opinion my be regarded as slander. If you want to start a separate thread trash talking me, the Sanctuary I've worked my tail off building, or the way I do things - be my guest, but it's a bit ridiculous to be posting this all on Terry's thread where he's trying to sell brackets. Everything off topic has been removed and I've responded to each of you personaly. You know how to reach me if you wish to continue in private.

to physically mount a V8 in an eagle (and I'm not counting all the other stuff ya gotta do), all that has to be changed over is to get your mounts, and that's pretty much it?  or did I miss something in a post?   I tried to read the whole topic, but my eyes went buggy.   :o

Post by: captspillane on September 26, 2011, 05:13:39 AM
The reason its so difficult is because the front axle of an Eagle is mounted to the engine. In a Spirit, you can buy fancy adaptors that have a 258 bolt pattern on one side and a V8 bolt pattern on the other. In a Jeep you get different metal L brackets and bolt them to the frame where the 258 brackets used to be. Both are bolt and go solutions. In an Eagle, however, its not at all the same. You have to make very fancy metal brackets that incorporate the axle supports on both sides of the engine. Terry has done a great job at making a very complex pattern that incorporates everything you need.

The next tricky part is that Eagles have the engine offset two inches to the passenger side to make room for the front driveshaft. A 258 doesn't have anything on that side of the engine, so it doesn't matter. On an AMC V8, however, there is a exhaust manifold on that side. You have to cut the old 258 mounts off the crossmember and weld on new mounts closer to the driver's side. The engine will still be offset, but it will be offset less than before. The lateral spacing of the new mounts is critical, so you have to weld it after everything is bolted together and squeezed in. I'll be supporting the engine with an engine hoist with the crossmember removed. It will be bolted to my factory T5 with its manifolds, front axle, transfer case, driveshaft, and full motor mounts all attached to the engine. I will then put the crossmember under the engine, shimmy it until I can tell where to weld, and then mark the crossmember and take everything back apart. I will be using a much stronger transmission than the T5 but I need it installed during this step to position the engine where it will be compatible with any factory transmission and driveshaft.

I've put information about the transmission options elsewhere in this forum. For an Automatic you definately want to use the TF727 because it shares the same linkages as our factory TF998s. Only use a TF998 or T5 if you have a 304. The 360 and 401 need stronger transmissions and rear axles to go with them. Most people will get the TF727 and AMC 360 together from a full size Jeep. Beware of the TH400, its the other common transmission in full size Jeeps. It must be avoided since its not compatible with kickdown levers, floor shifters, transfer cases, or even axles.

Plan on getting a Dana 44 rear axle from a Cherokee. The Commanche Dana 44 will also work well, but they have spring perches on the wrong side and no shock mounts. A Grand Cherokee Dana 44 has rear calipers, but they too need all their old mounts cut off. Ideally you should weld on new spring perches and Eagle shock mounts on any axle, but the Cherokee ones kinda work as is. One of the shocks will be on the wrong side of the axle and the perches are abit off, but it will work. I've also heard of some people doing well with Ford Explorer axles. The Jeep community also has directions to easily convert the Cherokee drum brakes to the Grand Cherokee calipers.

Flywheels are hard to come by. They're the same thickness as a 258 flywheel and have the same bolt pattern, but they are balanced specifically to the engine. I will use an Advance Adaptor between an NV3550 and a T5 bellhousing to retain the original flywheel and clutch linkage. To install my 6 speed NSG370 I will need to bring a 4.0 flywheel to a machine shop and have it rebalanced to match the flywheel or flexplate my engine came with. A 4.0  flywheel is a quarter inch thinner and I must use the factory slave cylinder because the NSG370 has an integral bellhousing.

I have a set of Spirit AMX headers that I will attempt to use, but I honestly don't think they will work. Everyone I know of has used the factory 360 manifolds (360 manifolds are bigger and should be used even if you have a 304) because only one pipe then needs to snake its way around the control arm supports and driveshaft. Its considerably more cramped in an Eagle than a Spirit.

The oil filter will not fit. You need a remote oil filter kit. The only one I know of is sold by bull-tear. There is also a rumor that a Jeep oil pan will not work since the original mockup was done using a V8 from a passenger car. A Javelin guy told me that the pans are actually the same. I'll have to flip my Jeep V8 over and try bolting the axle on when I get home to find out for sure. The high capacity Jeep pans are fatter and they definately won't fit.

I have pictures of a 304 installed differently in an Eagle. That one was fabricated to hang the axle from the front of the transmission. Those mounts are crude, hideous, and obviously weaker than Terry's mounts. For the amount of time and aggravation it takes to mock these up its well worth buying his. The only advantage I see of making your own mounts is that you can position the axle further from the engine to accomodate a larger oil pan or a lift. Terry put the axle as close to the engine as possible.  Even then I think it would be better to buy his and modify them than to start from scratch.

Thanks for that info Cats, as I am mulling over what to do in a similar case. I have a 401 and a 390.I was going to put the 401 in my AMX, but should use the 390 and get it rebuilt( as it was a stock gopac car). It now has a 304 ( non original) in it and will be pulled.Knowing I wouldn't gain much between a 304 and a 258 with a 4.0 head swap, the larger 401 seemed to be the ticket. Some may cringe at this, but haveing an extra wagon around, I am thinking of changeing to strickly RWD, looseing the front diff and transfer case ,adding on the extra limited slip I have, and makeing a drag wagon.Haveing to also stiffen up the unibody to do so is an added task too. Great explination !! Thanks

Post by: captspillane on September 29, 2011, 05:15:21 AM
I forgot to mention suspension upgrades. You shouldn't install a V8 without replacing your coil springs and leaf springs. The coil springs in 304 V8 Spirits are the same dimensions, but they use a thicker wire stock. There are several sizes of the heavier wire stock available that will work. The other options are found by searching for 1970 and newer Javelin coil springs.

AMC Eagles have a different length coil spring on the passenger side than the driver side from the factory. It helps with the engine offset. Coil springs are sold in pairs, however, so I've been ordering two slightly different coil springs pairs and then combining them to make a custom pair for two Eagles. You can compare specs available by searching through the different options available for Javelins at Rockauto. After comparing them, I don't think it is a big enough difference to bother doing that if you only have one car. 

The stock rear leaf springs are fine, but they are worthwhile to replace at the same time you're doing the front. SX4 leafs are especially prone to failure because the second leaf does not properly support the first one. I always replace the rest of the leaf pack with the heavier and longer leaves from a Jeep Cherokee. They are the same width. The longer second leaf supports the top leaf and prevents more of the same problems in the future. I also use rear shocks with coils integrated into them called "Load-leveler" shocks. They do a great job.

360, T-5, still alive.  The problem with T-5 isn't the tranny itself, it the operator.  Poor shifting techniques are what does them in.  My 360 is .020" over,  decked to 9.2:1, custom grind cam from LAZER CAMS, 4bbl Q-Jet, and 3" exhaust.  Not saying the T-5 can't be smashed, but mine came straight out a 179,xxx mile wagon, I have since put another 3 Moab trips on it, countless daily driving miles (before the straight axle).  And it's hanging in there.

If this isn't testing the torque capacity of the tranny not sure what is.

I'm just saying I wouldn't stall my V-8 swap just because I had a T-5.

I think I found these pictures from an ebay auction for a SX4 already converted to a 304 V8. The first picture shows the bulltear remote oil filter needed. The second shows the common problem spot on the passenger side. The engine mounts are welded to the crossmember with the exhaust in place to get it as close to that support as possible without touching it. It will not be offset as far as the 258 is.

The third and fourth picture show how pathetic and unprofessional this conversion was in comparison to Terry's mounts. I'm sure this set up worked just fine, but it sure looks shady. Terry does a rather nice job on his mounts.

http://www.advanceadapters.com/products/jeep-wrangler-nv3550-5-speed-transmission-to-jeep-258--v8-adapter-plate-kit/

This is the adaptor plate that allows an NV3550 to be installed behind a T5 or SR4 bellhousing. The input shaft is about 3/4 inch longer than a T5 input shaft. My Scrambler has this adaptor plate with its NV3550 conversion because it retained the stock flywheel and mechanical clutch linkage this way. My 401 V8 SX4 will also have this adaptor plate because AMC V8s are externally balanced and incompatible with 4.0 flywheels.

This next link is for the remote filter kits necessary because the oil filter doesn't fit with our Eagle crossmembers. This website also has a great number of AMC V8 performance parts.

Did anyone figure out how compatible the flywheels are between a 304, 360, and 401? How is this data given? I'm imagining a value in decimal inches of the distance of the neutral point in relation to the center.

I heard a rumor that the flexplate on my 401 could go on my 304 and the flywheel on my 304 could go on my 401 without any noticeable vibration issues. The rumor is that the 304 and 401 are nearly identical external balancing while the 360 is abit off.

One reason I ask is that I see new flywheels advertised to fit the 401 that also say it will work behind any 304, 360, and 401. It makes me question the interchange knowledge of the company selling the flywheel.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: carnuck on February 15, 2012, 06:00:59 PM
They bolt on, but a 401 would vibe with a 304/360 flexplate. The amount of weight is slightly greater as the engine size goes up. I drove a 304 with 360 flexplate and I could feel the vibe but others couldn't
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: hypereagle on February 15, 2012, 08:46:12 PM
All the weights are exactly in the same position.  The larger the displacement the heavier the balance weight. Also greatly depends on stroke versus bore. Dont remember which one was more significant.
Have seen a 401 with either a 258 or 304 flywheel. It did have a severe vibration.
 I once. Ran a 343 With a 290 flywheel. It too had a significant vibration.

  To Captain Spilaine
  Taking note of your knowledge and ability which are both very good. Im going to make a suggestion which I do not think will hurt the flex plate or counter weight. Use what I am about to suggest with your own discression.
  My suggestion would be to weld/build up the counter weight until the engine does not vibrate when revved up.
Don't let the heat sink into the flex plate and every thing should be good. Again caution! The flex plate is fairly hard and should not heated up too much. 

When I did my flywheel for my 360 SX4 I used the 258 flywheel. Got the dimension of the counter weight from a 304 flywheel. Used 4 different thicknesses of steel tacked them together and drilled them. Using a carbide with cutters on the end in a drill press cut a flat surface in the proper position of the flywheel as if I was using an end mill. Positioned the weights so I could center mark the flywheel for drilling and tap.

Once in the car bolt in bolt off until one of them (used only 1) worked. It worked very well. A combination of 2 or more weights could have been used. I lucked out with just 1.

Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: captspillane on February 17, 2012, 05:17:45 PM
Thanks Terry! You've got a very good thing going here.

I understand exactly what you did with your flywheel. I’m going to try a new unit before attempting to modify an old, but I do also believe that a flexplate can be modified without cracking if you are careful and preheat properly. "All the weights are exactly in the same position" is precisely the answer to my question that I was looking for. I cannot add weight without being confident where to add it in relation to the center point. I was concerned at the possibility of a clocking difference. I’ve actually found evidence online that some V8 flywheels did have their weights clocked differently but that won’t be a problem when adding or deleting weight from one V8 displacement to another. If you start with a V8 version you will already have a weight present to indicate the proper clocking.

I believe now that the rumor I heard was dead wrong. It said that a 304 and 401 were very close and a 360 was very different from the other two. In other words the rumor said that a 360 with a 304 flywheel would vibrate much more than a 401 with a 304 flywheel. I believe that rumor to be officially dead wrong because earlier in this thread Mav asked for flywheel weight numbers from an AMCA member. I presume he got them when he wrote this quote, "I've learned that the 304 and 360 flexplates are so close (down to the tiniest fraction) in balancing that they will work for each other."

Likewise you wrote that it was either stroke or bore that had a much greater difference than the other. I believe Mav is right that a 304 and a 360 have nearly the same balancing because they have exactly the same stroke. My 401 has a much greater stroke and bore than either.

As it stands I would be comfortable taking my 304 flywheel and putting it on a 360. That’s probably not a noticeable difference. It doesn’t help me much because I have a 304 and a 401 right now. I don’t consider the 401 to be compatible with any other.

My conclusion is that I need to match balance a 4.0 flywheel to the old 401 flexplate. The 4.0 flywheel will be lighter and a quarter inch thinner than an original 401 flywheel. The extra inertia of the heavier flywheel is helpful in a full size truck but my Eagle is too agile to need it. I also want to eliminate the need for my NV3550 to T5 bellhousing adaptor. It won’t be necessary with the thinner 4.0 flywheel.

That will also open the opportunity to install an integral bellhousing NSG370 6 speed later. Those are slightly weaker and age with less grace than the NV3550, but they do shift considerably nicer. Both are much stronger than an AX15, which is also much stronger than a T5.

I may have a 304 plate , I know I have a 401 and a 390 , wich may be the same as a 401, not sure on that.
I think I have flywheels and flexplates for the 390 and 401.I should look them over to match.

Post by: carnuck on February 19, 2012, 03:33:03 PM
I have a 304 plate (for TH400. 727 and 9xx flexplates are 4 bolts for the converter) The "notch" it's hanging from is all the way open on 6 cyl ones so all three openings are equal (zero balance). On 360s, the notch is smaller. On 401s, the notch is almost fully closed, or a weight is added to a 360 one

Does this kit relocate the front axle in any way? Will it work at bone stock suspension height? I'm considering this for an Eagle I may put a lift on. I'm thinking about 3" but would want the axle mounts lowered to avoid joint binding. Are the lower arm mounts incoperated in this kit and could they be lowered as well?

I did an SX/4 a few years ago with a 4.0 and a 3" lift with spacers on top of the springs and the front axle mounts lowered about 2". It worked every well for me. Sold it and I'm now thinking about another SX/4 but with a V8 swap this time.
Title: Re: hypereagle's AMC V8 Mounting Kits
Post by: captspillane on October 03, 2012, 06:15:36 PM
Generally a 3" lift isn't possible as you described. More accurately you lifted it an inch or two at the most from stock height, which is easily an inch or more higher than where most Eagles sit today with their antique coil springs. A true 3" lift has been accomplished by others here on the nest and it was much more involved.


The steps you took to lower your front axle 2" on your last car are the exact same steps you'd have to take with this kit. The kit is two sets of engine mounts and another set of plates that weld onto your existing crossmember. The engine mounts include an intergrated piece of metal that sticks down pretty far for the two side bolts on the side of the axle. On the original 258 this used to be accomplished by two pieces of metal instead of one, the metal plate at the engine mount and another long thin strip of metal that bolted to the rear of the engine on the driver side. Keep in mind that the oil pan is bigger on a V8, so Terry had to position the front axle nearly touching the oil pan to keep it at stock height.

360s were used until the end of the classic Wagoneers until '91. 401s are harder to find and in high demand. 304s were very popular as a step up from the 258 for most AMC vehicles, but they ended around '81. 360s were vary popular and should be easy to find.

hey, i have an 81 kammback 2x4. interested in the mounts. thomjoad@verizon.net
  Hello All, been awhile.  To answer the idea of putting a V-8 in a small car, even a stock one, would be very dangerous unless you are capable of handling it.  I took a '88 Concord v-8 and transferred every part of it into a '81 Sprit, to include suspension ,trans ,rear etc. Everything fits, just have to figure out which mounting holes to use. Most of the holes are there, just have to dig them out of the dirt and grim.  Only mods I had to make is the driveshaft, was about 1" to long.
  It was heck on wheels. Couldn't get on the gas too hard or you found yourself going in a direction you didn't want to go.  Was a fun car, sorry I sold it. If it is still running it should be in the Joplin,Mo area.
  Looking for another one now, sure are scares.
