MD how much boost do you know? My motor makes aprox 470 flywheel so a set of twins should help it out I am wondering how much hp I'll have with only running 7psi.......
He told me 13lbs of Boost it made 911RWHP with a 340CI W2 Headed Motor..............you would trip out on the internals of that engine also no high dollar 4340 parts either and a Stock Block to boot!
