I agree with the judgement about the front styling. I've always like the Gen 1 grill, hood and headlights better. Did this project ever get off the ground ? MHF

Holy thread resurrection ! To answer the question, technically no carburetor is "too big". The ability of of larger CFM carburetors to effectively atomize the fuel at slower airspeeds is the culprit. Careful tuning and possibly annular boosters would get you there. More pump shot through a slightly larger squirter would give you a longer steadier accelerator pump fuel supply. A 2-stage power valve might be needed as well, but it can be done. This of course doesn't speak to the myriad other vacuum lines, and gizmos that were part of '80s pollution control technology. Vibration issues aside, the 390 CFM 4bbl could be made to work as well if you can fab up a proper manifold and plenum for it. MHF
