Well, if you allow 30% loss in the drivetrain, it's makin' 470 at the flexplate. Pull the plugs, wire the throttle blades open and check cylinder pressure. I think I'd have backed off on the intake volume in the heads if I used a cam that made power to 7,500. In my opinion, you've got more heads than cam.

When I was looking at head flow numbers, the Vic.'s did not flow as well as AFR 190's or 195's. Now I have to decide how to pick up the torque. Smaller runners? Or will a cam with less duration and overlap raise the torque enough to bring the hp. up enough at 6500 rpm? (I don't have to rev. to 7000 rpm). My cranking compression is 150 psi.
