Pontiac's don't like single plane intakes and big cams such as your RAIV unless you have the gearing AND compression. They also like tight tolerances and tight assembly (minimal vacuum loss) Pontiacs also LOVE demand orientated carbs such as the Q Jet over a double pumper Holley. Perhaps I am biased here...but I've never had luck dialing in a Holley nor have many who have tinkered with, run and written about the various effects of head, cam, carb and exhaust (Jim Hand)
