Good post Joe. Maybe we can all get along now. Me, you, mrfixxall, mike Tkach , and Jeff Armstrong. Sooner or later we're all gonna be on a poker run together.
Maybe if you get these engines straightened out, you'll finally be able to keep up with mike Tkachs fountain .........

The cam in discussion was for a procharger engine. His problem was idling issues, and getting on plane. Engines made 1300hp at 6500,, torque peaked at like 1083ft lbs at 5900. However tq a 3500 was 788. That was where they started the pull, but my guess at 3000 he was barely making 600ft lbs when not making boost. Planing with 120mph props with 600ft lbs on tap wasn't very impressive to say the least.
These are very low 7.8:1 static 522's. his duration was 252/262 on a 114. My overall advice was to bring the duration numbers down, to help build some cyl psi down low. The torque peaks right now where his hp should. Not enough static compression to be runnin the cam he was in a marine 522. Just my thoughts but I'm no expert .
