i recently purchased a set of trick flow twisted wedge heads 195cc 64cc 2.02"/1.60" aluminum heads, comp cams 1.52 pro magnum roller rockers, a single plane intake (not sure looks like the edelbrock scorpion), and an edelbrock 750cfm carburetor.

this is all going on a 3970010 350 4 bolt .30 over with a crane energizer 10052 .454 camshaft and .30 flat top pistons.

im trying to get into the 12's, but im not sure my camshaft is big enough. ive heard many issues about the TF heads and flat top piston clearance issues. i know there would be an issue with the small camshaft i have, id like to go to a .484 lift or .490 not to big like the crane energizer 10072, has .480 lift 2800-5800, but id like to know if there would be any clearance issues? is it worth putting a cam with only another .30 lift?

has anyone had this combination? trick flow twisted wedge heads and flat top pistons? what size camshaft did you run.

 

ive done a search and as far as i kno wim safe from valve/piston clearance up to .500 lift maybe even .530??

anyone correct this??

 

one more questions...


with the crane energizer 10052, if i was to go to a different camshaft will i need to get new lifters? or can i keep the same ones i have?
