My motor is a 350 w/ stock flattop pistons(4 valve reliefs). It has fresh 882 heads w/ 1.94/1.50 valves and gasket matched intake ports. I'm using an edelbrock performer intake and 1406 carb (jetted 12% richer than stock). The cam is a Crower 267 HDP (210/216 dur. and .444 lift). My cyl pressure with this cam is 150 psi. I was wondering if a larger cam (221 dur. and .465 lift) would improve my ET's even though I'll lose 15psi of cyl pressure?
