Quote: The only downside to running a roller cam is cost. Part of the additional cost besides the cam and lifters are valve springs, pushrods, cam button, and bronze distrubitor/oil pump gear.
With a big block maybe, smallblock not so much since the factory churned them out in huge numbers from 88-03.
All you need is the cam and new springs.
I picked up a used ($175) .505 lift Comp Cams roller for my 5.9 Duster and it dropped right in. Stock pushrods, lifters, cam gear and rockers.
Big block is a different story as there isn't any factory pieces to fall back on.
