Piston to valve clearance, rocker ratios? So, I have a chance to grab up some comp roller rockers for over 1/2 off. New, unused. Question is, since I would be going from 1.7 to 1.75 ratio, will my cam be ok, considering piston to valve clearance?
Cam is 227/230 .614/.609 111+2 LSA
math tells me the lifts would change to 227/230 .632/.626 111+2 LSA
Would the piston to valve clearance be ok? Heads are stock 243s, stock stroke, stock head gaskets (may use LS9 head gaskets if possible, cause I can get them cheap too)
Would this mess up the specs on the cam to where i would actually make LESS power?
Previous setup made 430whp, 390 tq.
Thoughts?
