Part Number: 300-945

Holley Hi-Ram EFI intake manifolds are now available for 1965 & later 396-502+ MKIV-MKVI Big Block Chevy engines with standard intake flange rectangle-port cylinder heads. Traditional Big Block Chevy engines can now also be fitted with the Holley Brand Hi-Ram type EFI intake manifolds that have so well served GM LS & LT, Gen 3 Hemi, SBF Ford, and Ford Coyote engine platforms. The iconic Chevy SBC & BBC platforms are primed for 21st century induction systems, Holley EFI engine management, and Holley fuel systems.
