What kind of cam will you be running and what will your valve spring pressures be? Anything up to about 400 hp you can use a Summit double roller, anything more radical then that and you would be better served with a Cloyes double roller.
Don't forget to drop in a MP cam chain tensioner while you're at it.
Running the MoPar 508 cam, Edelbrock RPM heads. The Cloyes was what I was running. I would run that again. Very good chain. Just wondering if their are any better ones.
this is just a thought.. if u spend a day degreeing the cam.. u wont use a rattling std aftermarket timingchain that will stretch to the moon and back within a few miles.. we are in the 21st century now.. buy billet and add the v6 tentioner with it.. then u can take it with u to the next engine when this one gave up.
