Supercharged Smallblock Combination.

Iron heads cant make as much, no matter how nuch force you use to push the air thru. The problem is cross section..Most iron heads (Baring W2s) dont have enough to move the air volume required. You boost is backpressure in the intake system..That's what it's hitting for resistance. Like water in a hose, or oil flow..Press is a resitance to flow..Not the flow itself. Smaller port will reach 10psi faster, especially when paired with a larger blower, even a centrifical model. And that 10 psi will make less power overall, then 10psi of boost with something say 20% larger in cross section. Also, you want to be sure that the engine produces 750hp at the crank, when under boost. If it were me, I'd run an intercooler, and ditch the carb idea too. Not having looked to see your flow numbers, I'd say you will fall short with any factory iron head I'm aware of, even in ported shape. Also, for the intake, your midrange is produced by the blower..As is your top end..The only thing to keep in mind would be low rpm operation, because it wont be moving a ton of air right off idle. But, that's also what the convertor is supposed to help with. Blowers and turbos are different animals..Not my strongest area either..You may want to hunt around for some info on designs before you continue buying stuff. just my $.02..
