I know theres alot of threads about timing chains, but not finding my for sure answer. Will a double roller fit a LS2 with out clearancing? If not how much clearancing has anyone had to do and with what chains. Also at what point is a double roller needed over a single roller aftermarket chain.

I have an 07 LS2 block with a 402 rotating assembly, already have a ported factory oil pump from texas speed, just trying to decide on the right chain.

Thanks!

 

Just get a C5r timing chain, no need for a dbl roller. Just have a good balancer cause harmonics break chains bud.
