I think it might make more power than you think at higher rpm.
Current engine makes ~275lb/ft @ 8000rpm = ~420 hp
With a 10% larger displacement, more aggressive cam timing, some headwork, exhaust, etc, if you saw ~300 lb/ft @ 9000 rpm, that's 515hp.
The point of the exercise would be to move the torque curve up in the rpm range, while strengthening the engine to handle the additional rpm.
I started thinking along these lines reading about the Ferarri 458 Italia engine, which is quite a miracle: 4.5 liter V8, 14:1 compression ratio and 605 hp @ 9000 rpm.
RPM is power, if your engine can hold together.
