The Carter AFB Competition Series was a high-performance aluminum four-barrel carburetor introduced in 1957 and then reintroduced in the 9000-series by Federal‑Mogul/Edelbrock. A favorite for enthusiast purposes, the Series is available in 500, 625, and 750 CFM ratings and offers manual choke and choke-less versions . Mechanical secondaries together with four-metering jets that have stepped metering rods and springs give this carburetor phenomenal throttle response, strong acceleration, and good fuel economy when properly tuned . The Competition Series types consider transition circuits with a richer setting but have no secondary throttle lockout so they may serve best off-road or on the racing track This versatile carburetor and simple-use AFB is fairly popular in street-strip use when tuned right, coupled with its tough construction, that is suitable for a wide range of applications in classic V8 engines.
