I think the crankshaft HP will be more in the 440-450 range. The combination sounds good but your real HP limiting factor is the cubic inches. The other issue I see will be traction. That considered, I would say 7.90 - 8.20, in the 8th. Theoretically, there is more e.t. in that HP. I'm just thinking that without slicks you will not see it...
Do yourself a favor and keep the max RPM's and shift point more in the 6800 or so range. I don't think there will be a difference in 6800 and 7200, but your engine will last longer at 6800.
My opinion is worth just what you paid for it.
Good Luck & Great Racing ! ! !
