70 340 HP handling ability.

Damn fine points and I cannot argue with them. I will say this after you build one it seems like it was easy. You look back and say “that wasn’t too bad”. I built a set of under chassis headers from scratch once and that was way worse than any turbo parts I’ve ever built. FYI the engine management will be the same for turbo/supercharger.

For sure I could see that, don't get me wrong I really want to build a turbo V8 Mopar and plan to do it some day. But right now I don't have a good indoor spot to park my Duster and still have room to work around it (garage is tight), and I don't even have a damn welder lol... My 360 has Cometic head gaskets and head studs with only 9:1 compression so it's just waiting for boost and the fact that I could basically bolt on a Procharger kit in a weekend or two is extremely appealing. And regardless whether I go turbo or blower I first need to seriously upgrade my fuel system and convert to EFI (prefer that over blow-through carb).

Sorry if I'm hijacking but hopefully this talk is of some use to the OP...?
