Depends on the cam. Give us the specs. and we can get pretty close.

Lots more details would make the guesses closer to the mark.

Cylinder head flow numbers, valvetrain specs (Rocker ratio, valve spring pressure), exhaust header diameter and length, exhaust system diameter, ignition system, ram tube length, compression.
