So my original idea for this combination didn't work out so I have decided that I was going to try to check out the SHP Dart blocks either the 372 or the 400 block but i hear the 400 dart block mostly benefits from carbureted intakes and I'm not trying to go that route if that isn't true with a good aftermarket tpi style intake like a tpis intake, pro flo,or stealth ram then that's fine but if the 372 version works better and More close to my original idea witch was a 383 build that would be great as well my goal is to build this motor to around 500 hp n/a and around 700 hp with boost I already have a cam which is a tpis zz409 so I'm hoping to still use that at least thats pretty much were im at
