Engineered as a direct replacement for the Edelbrock 1406 Performer, this 600 CFM 4-barrel carburetor with electric choke delivers precise fuel-air mixing for small-block and mid-displacement V8 engines! Its downdraft design integrates an 18-gauge steel air cleaner for low hood clearance, while dual vacuum ports (timed and full vacuum) dynamically adjust ignition timing. With a 2% leaner calibration than standard models, it balances aggressive throttle response and fuel efficiency. Perfect for Chevrolet 350 V8s, Ford 302s, and custom builds—upgrade your ride in 15 minutes for street dominance or track-ready performance!
