    Introducing the Proform Race Series Carburetor — a premium, U.S.-hand-assembled performance carburetor engineered to deliver serious gains in throttle response and airflow for both street and strip applications. Built from high-quality aluminum, this unit features a next-generation main body with contoured venturis and 2-step down-leg boosters, offering markedly improved fuel atomization and airflow control.

    Designed for the serious enthusiast, the Proform carb comes equipped with billet aluminum throttle base plates and metering blocks, along with adjustable screw-in air bleeds for fine-tuning. These enhancements reduce warping, maintain stable performance under load, and encourage more consistent runs.

    What sets this Proform Race Series carburetor apart is its versatility and user-friendly design. Whether you're building a high-revving small-block or a boosted monster, the high-flow main body and robust internals let you dial in just the right setup. With no choke tower (in many versions) and optional dual-feed plumbing, it simplifies your install while maximizing performance.

    In short: if you're searching for a carburetor that blends race-proven features with precision tuning capability at a great value, the Proform Race Series is your solution. Install it, tune it, and unleash more horsepower with confidence. Upgrade your fuel delivery today and get ready for gains you can feel the moment you hit the throttle.
