As of right now mileage is not a concern! More worried about max performance

A properly tuned Quadrajet would be my choice for your druthers. The trick is, properly tuned.
As for which Quadrajet, I would talk to Sean Murphy at SMI, and get one from him specifically set up for your build. He will want to know the intake manifold, the exhaust, the displacement, the camshaft, the heads. Then he will build the correct Quadrajet for you. There are lots of little air bleeds and such in the carb that GM set up for each engine at the factory. You can't just bolt one on and expect best results.
What Sean Murphy doesn't know about Quadrajets isn't known by anybody.

Mark (Quadrajet Power) on this forum will custom tune a Quadrajet for you as well. See his reply above. I don't know Mark, but others have said good things.
The point being, don't buy a generic Quadrajet or get one from a junkyard or something. There's more to it than that, and you need someone who knows what he's doing unless you've been around the block a couple times and are willing to experiment. And have a good wideband A/FR meter.
