700HP 383 Buildup

it all depends..is it going to be EFI controlled, or blow thru carb? Intercooled? what supercharger? what pulley? You could make 350-500 or so prety easy. The down side is, to make big boost with a centrifical supercharger, you use up 15-20% of the power made just to turn the blower. That's why I wouldnt use one. I'd use turbos. Less boost, and much less parasitic loss, from the same support systems (if it's going to be EFI anyway).
