I have an 83 eagle that a bought a new 4.2 motor for. It has an automatic transmission, AC, cruse control and a rats nest of vacuum holes. My new long block came with the head and its for the 79-80 model but I have the new valve cover needed. Looking for a simple daily driver. So my question is what changes can should I make. I can do some work but I be having a shop do most. I also picked up a Weber carb and CRT performance HEI distributor from ebay. The distributor in new the weber is used. The vacuum and car has been screwed with a lot. Also the car will not have to pass any emissions tests.
I don't mind putting a bit of money in to it but I did already buy the long block. Whats a good carb, distributor, and any other stuff to use/do? Thanks
First make sure that motor has the same mounts for your front axel. So compare your motor mount points between them.
I have heard from people who put a weber on their cars and jeeps and hated it because they are a son of a gun to keep tuned, I was told that if i was thinking of a weber to ditch that plain and go straight for a MC 2100
If you want my advice on the vacume lines. rip it all out! Just have the necesities coverered and don't worry about anything else. I've removed vacume lines on probibly close to half a dozen eagles and all of them ran much smoother without the plastic rats nest that is the vacume lines. if you like I could probibly even get a picture of my SX/4 and how I routed the lines on that to give you a refrence point on what can be taken off without having to trace every bloody line.

What needs to be changed to use a MC2100? looks like the Weber is staying in the box I don't want to have to screw with it all the time.
ETA found the adapter kit ;D to use the 2100 link removed -- folks will have to do their own search there.

I would Love to rip all of it out I just worry I will rip something I need out. I do not care about the cruse control or anything really I had a 82 for a bit and it was clean and simple under the hood. Thats what I want my 83 to look like. My lines have been mixed up and screwed with by more people then just me :'(
ETA ...

Man I hope I didn't buy the wrong motor. What am I looking for with the front axle mounts?
Here is a link to a thread with a modified vacuum diagram. http://forums.amceaglenest.com/index.php?topic=8109.0 This digram was drawn for the Carter BBD, but can be easily changed to accommodate the MC2100 and covers the basics with no smog control devices. Also, here is a picture of my engine with the MC2100 and the GM HEI setup.

The last picture shows the HEI peeking out.
Hope this helps.

That's what I want ;D I talked to a local jeep shop today and the guy wants to use a holley 2 barrel not a Motorcraft 2100 for some reason would that be OK. From what I have read everyone likes the 2100 but the mechanic that will be doing my swap. :-\
If you look closely at the 2 carbs you will see that they look very much alike. On some of the MC21XX models, you may even find a Holley stamp on the body of the carb.

So it's not that one is more reliable or "easier" then the other? If the holley is almost the same thing from a MC2100 I shouldn't try to talk him in to using the MC2100? I know the guy on ebay sell's the MC2100 with all the adapter stuff, will I need the same for the Holley or is it a mass produced after market adapter for the Holley? Thanks
if it where me I'd go with the seller on the bay for everything ..... he has sold TONS of those kits. Plus your the one footing the bill for all of this so it should be up to YOU what goes on your car. I work in a body shop for a living and when someone tells me they want pink car i can't just paint it red because that's what i want to do. You might be better off looking for a new mechanic who wants to be paid to build an eagle for you
In my opinion, the MC2100 carbs are easier to find, in that they are in junkyards every where. They are much cheaper to source parts for. I really don't think you will see much performance improvement with the Holley over the MC2100 on a 6 cylinder engine. If you were to ask me about the difference for a V8, I would probably go Holley though.
