HP = rpm x torque (approximately). More power from: mandril bent headers, cam (I have one too wild for road use), free flowing inlet, massive tune up then dyno time, gasket matching head ports, polish of inlet manifold internals (matte finish), raising the compression ratio, building the engine again and a tunable EMU. How's that?

Depends on three things. 1)Your skill level; 2) Your tool kit; 3) Your contacts (i. e. who you can get to work cheap for a friend).
