The Braswell B-4760 Severe-Duty™ carburetors have become the benchmark for racing carburetors throughout the industry. These carburetors are manufactured from a lightweight, high quality aluminum die-casting. They utilize an improved air entrance combined with our CNC profiled venturi to provide maximum air-flow for any given size. This allows the use of a smaller venturi for better throttle response, fuel metering and atomization. Metering is handled by billet aluminum metering blocks that are fully adjustable. The engine can now safely operate at a lower BSFC, and when properly tuned produce improved on track performance, fuel mileage, and engine life. Our lightweight Bat™ bowls fitted with Severe-Duty™ floats that are set up for the specific application are standard. B-4760 carburetors are also available with upgraded Patented Fuel Chute™ float bowls. The assembled main body is then mounted on to our Severe-Duty™ dual bolt pattern throttle body assembly equipped with triple ribbon throttle shafts for smooth operation and durability. All components are specifically engineered and calibrated for race applications, not converted street car technology. This means you won't find any unnecessary material or corners cut to utilize existing components.

     The B-4760 Series carburetor is offered in three Spec sizes, a 600 with 1.22" venturi and 1.575" throttle bore, a 650 with 1.25" venturi and 1.688" throttle bore, and a 750 with 1.375" venturi and 1.688" throttle bore, designed for Spec or Crate Motor classes. Braswell can work with sanctioning bodies to provide simple gauges to insure fair competition and simple tech. For open competition classes, these carburetors are available with venturis from 1.25" up through 1.48", and throttle bores in either 1.688" or 1.750" to accommodate the needs of most racing engines. Unlike other carburetor shops or builders that just take something off a shelf, this allows Braswell to custom size and calibrate the carburetor to the specific needs of your type of racing, engine, chassis, fuel, track, and driving style.
