Well I have decided on using KB16-60 Hypereurectic pistons. 1.765 compression height .180 dome with the stock 6.135 rods and stock 3.76 crank. This with the COMP CAM 11-209-3 .507/.531 lift and 219/229 duration with 1.72:1 rockers, flat tappet hydraulic lifters and appropriate springs. From many hours calculating I believe I will have about about at least 0.08" intake valve clearance and over 0.1" exhaust valve clearance I hope. Of course I will verify these numbers upon assembly. From what I have calculated I hope to get 440hp @ 4000rpm. This is with a 500-550 cfm carb. I think about 9.84:1 compression.

Anybody have any suggestions/input? Pie in the sky or what?
