Rochester Quadrajet 4-Barrel Carburetor - Used, Untested

Rochester Quadrajet 4-barrel carburetor, cast-aluminum spread-bore, marked 'GM / Made in USA / Rochester Quadrajet.' Used, untested core-grade unit — complete with throttle plates, choke and accelerator pump linkage, and both mounting ears. No legible stamped list number in photos, so marine vs. automotive origin is not confirmed; Quadrajets were used on GM V8 cars/trucks and on marine V8 sterndrives (MerCruiser 5.0L/5.7L, OMC Cobra 5.0L/5.7L). Marine and automotive Quadrajets are not interchangeable. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
