⛽ Holley 4-Barrel Carburettor
The Holley 4-barrel double-pumper is the muscle car carburettor, used as OEM equipment on virtually every high-performance American V8 from the 1960s through the 1980s. Pontiac GTO, Dodge Charger, Chevrolet Nova SS, Ford Boss 429, and Dodge Challenger all left the factory with Holley 4-barrels in 650–780 CFM flow ratings. Because all American V8s of this era share the same flange bolt pattern (Holley 4150/4160 series), carburettors cross-fit between makes and models without modification.
