Maybe. I've gotten away from the "traditional" holley carburetors, because they offer such little tuneability. I have a Quick Fuel 450 vacuum secondary four barrel on mine and have it tuned just right. They have adjustable idle fuel restrictors, high and low speed air bleeds......they're SO much more adjustable than the Holley ever were. Holley now sells some like that, but you're gonna PAY for it.
