A-bodies at F.A.S.T.

Rob, the carb does not need to be numbers correct but you can not replace a 650 with a 750 and you can not use an Edelbrock replacement. You can remove the choke linkage but you can not mill or remove the choke tower, it must appear stock. KInda hard to get a 650 CFM AVS to flow enough to feed 500hp.

You are allowed to upgrade to a 2.5" exhaust, X pipes and H pipes are legal. No welded or Chambered mufflers. That means something like a Dynomax super turbo or ultra flow but no Welded race magnums or Flowmaster, Spintech or areo chambers.

You also need the correct casting number heads and intake and must run in the original size rim for your car. If 15s werent available you cant run them. But I think if your car came with E14s or E15s you are allowed to upgrade to G14s or G15s.
