Cam selection help please

Sorry, I meant fit as in P to V clearance. However I just found out from original owner that he had valve reliefs ground .040" into the intake side of the pistons and that the piston is .090" in the hole at TDC. He was running a 300 duration cam several years ago, but couldn't remember the lift.

.090 in the hole won't ever have trouble with cams like we're talkin about....and it is the duration you have to worry about.
