67 Cuda: disappointing dyno numbers, need some advice!

A good 3500 converter and a minimum of 3.73 gears (3.91's would be better) and I don't mind that cam. I like the lift. Not sure, but if I had enough intake valve to piston clearance I'd think about a 100-102 intake centerline, mostly because I doubt your compression ratio.

I have A 833 OD transmission with 3.91 gears. A buddy said we could check clearances with a checker spring and dial indicator?
