timing chain

[amcfool1]

hi, I'm in the process of building an 84 258 for my 84 sedan. This is to be a street car, a daily driver. Any opinions out there on the best timing chain? On my last build I went with a  Mopar double roller ( Which is just a repackaged Cloyes) no problems in 15 years. Now, I'm told that with a Cloyes true roller, one can't use the oil slinger, and this may cause a problem on long highway trips. My 82 went several times from Roanoke VA to Chicago, in one day, no problems, and is still going strong, it was built in 2001. I didn't build it myself, it was professionally done, so I don't know if the oil slinger is there or not. The current thought is to use a 4.0 timing chain, which is, as far as I can tell, a single roller, but not a True roller chain. The price difference is huge, about $40. for the 4.0, and about $150. for the Cloyes True Roller, ($172. at Rockauto). So, my option are: 1)stock style silent chain, 2)4.0 single roller, or 3) Cloyes double true roller. I welcome any and all opinions/advice. I'm thinking of using the Crower Compupro2 cam, #44243. thanks. gz

For a street car the Cloyes single chain set will work just fine.  That is the one most of us have gone with when we renew the set.

hi, and thanks for the reply. do you mean the single roller for the 4.0? gz

When I replaced mine on my 87 Eagle, I just made sure the timing chain gear and set was made in USA!

when i made both of my strokers i only made sure the chain was tight. than i went with a domestic cheap chain for a 4.0l. i think one of those motors has the oil slinger and the other does not.

Note that there are 2 different 4.0L chain and gear sets. Around '91 they put 5-10 degrees retard into the cam gear to do away with the EGR valve. Adding a 4.0L timing cover and cam bolt may help in the long run because of the cam button.

hi carnuck thanks for the tip will the 4.o timing cover bolt right up to a 258/  and what does a cam button do? thanks gz

The cover will bolt on but you my need different spacers. Save the 4.0L bolts. I'm putting the 4.0L accessories in my Jeep with the older style alt.

Here's the one I installed on my engine rebuild. It's the Cloyes True Double Roller Timing Set, and I fit the oil slinger in front of it without any clearance issues. It had 3 different timing positions; 4 degrees advance or retard, and TDC. I set mine at 4 degrees advance for more low end torque, and I have it hooked up to an Isky cam with .450 lift on intake and exhaust.

You have to be careful because it depends on the offset of the cam grind. Not all are done straight up. If you get too far advanced, then the motor won't stop pinging and will have trouble getting RPM.

btw, the cam button upgrade is still available from MOPAR for the 258, about $8., gz
