Cam is small so that will restrict the power but you should have great torque. I'm going with 650 torque and 525 hp as a guess. Hopefully it starts, runs good and doesn't leak. If it does those three then it is a successful dyno day. Fine tuning can always take place down the road. Are you confident of the EFI tune at this point or will you need to dial in that tune on the dyno?

I think you're a wee bit optimistic. My guess is 542 hp and 649 lb/ft.
