638 on the Lift, 242 / 248 with a 112 1/2 LSA, you may want a couple more degree on the exhaust for the Procharger.

yea but the goal here is to keep my RPM band lower... 2800 - 3000 to 6000 RPM max... I think this is the wining ticket. We will see in 3 weeks.

7500rpm would sound cool, for a few seconds at least !

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 .
Less duration could help. A smaller pulley would definitely help.
