427 Carburetor

[Boomer427]

What would be the the best size carburetor in terms of CFM for a 427 street/race engine?

Best size? Man theres a loaded question.

OK, I've got TWO 660cfm four barrels on mine, 1320 cfm total. RADICAL cam, roller lifters, hi-rise manifold and one MEAN engine that is BARELY street friendly.

I would think 750cfm is plenty for a decently built but not "over the top" 427.
