I'll say 720 at 6200, the combination of the small exhaust tubes ( collector size is 3.5 so it's probably not quite as bad as it looks ) and EZ-1's built-in 'kinda meh' exhaust flow (compared to a raised port) is going to force the peak RPM to be a tad to the low side, peak torque should come in around 5000 but with the cubes and CR it should be EPIC all the way there. The wider 112 centers should help the torque hang on a while though. An exhaust limited low Peak torque RPM has a way of lowering the HP curve trajectory, but there's F.A.S.T. ways of getting the torque not to drop like a stone.

The guess is on the high side for most but I know Dwayne knows how to make the most of that EZ intake port.

I was gonna ask why not use a raised port but then I realized you probably are dealing with something that might have to fit back into a Fishbowl
