750CFM Race Series Carburetor

The 750 CFM Race Series Carburetor is a high-capacity four-barrel fuel delivery system engineered for serious engine builders and performance enthusiasts seeking maximum fuel atomization and flow under full throttle. This square-bore, no-choke design delivers 750 cubic feet per minute—ideal for naturally aspirated engine displacement in the 450–550 cubic inch range and modified smaller-displacement combinations requiring aggressive tuning. The mechanical secondary operates independently of engine vacuum, ensuring crisp throttle response during hard acceleration and consistent fuel metering across the entire RPM band.

Constructed from aluminum and finished in purple anodized tumble-polish, the carburetor weighs 9.25 lbs and measures 12.5 x 8.5 x 14 inches, providing a compact footprint suitable for tight engine bay installations. The dual-inlet configuration simplifies fuel system setup and improves distribution consistency. The square-bore platform accepts a wide range of aftermarket intake manifolds and adapter plates, allowing seamless integration into both street and race applications. Lack of automatic choke means this unit demands manual priming on cold starts—a standard requirement in dedicated race engines where driver control of initial fuel mixture is preferred over warm-up enrichment circuits.

This carburetor suits builders targeting 450+ cubic inch engines, high-lift cam installations, and peak RPM operation in the 5500–7000 range. It is not recommended for street applications requiring smooth idle and automatic enrichment. Buyers should verify intake manifold compatibility and ensure fuel delivery pressure is correctly regulated before installation. The mechanical secondary system requires proper linkage setup and tuning to avoid flat spots or hesitation during transitions. Purchase includes a single unit; mounting hardware, gaskets, and fuel lines are sold separately.
