How much hp do you need, what fuel to run?
I had built:
350 main bearing block ( Dart )
compstar crank w 4" stroke
4.165 bore with je pistons 14.7-1
pontiac 867 heads victor jr 4500 intake
alcohol injected
vac pump
aprox 800 hp
(note heads ported by self at 350 cfm intake at .700 lift )
should be a good combo
