I'm doing a cam swap and I need a new timing chain. I want the lt4 chain, do I need to get the whole set with the cam and crank sproket, or can I just get the chain itself? That and what would be the best roller rockers for a cc306?

 

Timing chain depends on what opti and timing cover you got. For RR's you may as well do 1.6 while your in there replacing valvesprings and stuff anyway. Plus their good for a few horses! I'd personally do non self-aligning RR's with hardened pushrods and GM guideplates for a sturdier valvetrain since you have to rev high with that cam.

 

if I kept the opti and cover stock, what would I need?

 

Well what year is your car?

 

Its a 1997 z28

 

You can't just use the LT4 chain, you need the sprockets as well as the LT4 ED chain will not work with the stock LT1 sprockets.
