Looking to replace my timing chain to possibly regain a few HP and try and eliminate some ping I've got. (intake plenum gasket already replaced, CCC, etc...)

Figure since I'm doing it, may as well go with a double roller.
Anyone know for sure if the old 360's use the same timing chain as the Magnum 5.9's? I see lots of references to 360 timing chains, but none that specifically say for the Magnum version..

Thanks
Bill

I'll have to admit I'm thoroughly confused about the 360/318s of yesteryear. I think the Magnum motors are different, and parts aren't interchangeable. I've seen so many different performance accessories for the oldschool 318s and 360s but virtually nothing for the new Magnum motors. The aftermarket sucks compared to the older motors.

anyone else?

I know that you can swap magnum heads onto a older block, so I was kind of assuming that the top end was where the majority of the changes are.... ah well... I can always check with a few mopar buddies, but since it's a slow day at work, thought I'd post here! :D
Thanks for the help!

Maybe but you can't put the valve covers on there. They leak like crazy.

If you look at Summit's online catalog it lists different part numbers for the older and newer 318 parts.. I'm pretty sure that there's not a whole lots that's compatible, but I could be wrong. Call Summit and ask?

Ok... for anyone else who might care... There are different styles, there is a three bolt mount and a single bolt mount.

For my 98, it appears the correct double roller chain (single bolt) is Mopar # P5249267.
Guess I'll find out for sure when it comes in.

Thanks
