the cam grind determines the lash , I also have Oregon cam that going in my cam, follow the instruction of cam . . make sure you don't have a intake manifold leak
Yeah, those are the questions I have, is this an OE cam,...is the PCV hose intact/secured,...same with vac adv to dizzy,..?
There is as much as 16deg and .050"lift of difference from an early Slanty to the early-mid '70's Slanty cams, (excluding the Hyperpak). Tweaking out that extra .003" may show a viable bump in the bottom of the later cam, not buyin' it on an earlier one.
