I would love to see what would happen if you put an Isky RR735 rollercam in it. The cam is 278/288/110 . Intake lift is . 735 with a 1.5 rocker, lash was(?) .026 . .200 diration was close to 200 on intake, but it needs good valve springs. Not sure how much overkill i had, but i used Comp 947 tripples at 330 on the seat. Up the compression somehow to as much as you can run, and mid nines at 3500 lbs could happen. That cam was making 800 hp by 5700 rpm in a 4.5 bore 528 at 13.5 compression and peaked at 847 at 6900. I was using 1.55 Jesel rockers and . 043 rings, which from what i understand make a difference . But i like the power curve on that cam. It didn't seem to want more converter than about 5200 to 5600.
