This configuration refers to a specific induction system designed for the Ford 302 cubic inch V8 engine. It involves a manifold designed to accommodate a four-barrel carburetor, a device that mixes air and fuel for the engine. This type of carburetor has four venturis, or air passages, which allow for a greater volume of air and fuel to enter the engine compared to a two-barrel carburetor, leading to increased power output. This setup was a common performance upgrade for various Ford models equipped with the 302 engine.
A four-barrel induction system offered a significant performance advantage, particularly in applications demanding higher horsepower and torque, such as muscle cars and trucks. It delivered improved throttle response and high-RPM power compared to the standard two-barrel setup. This modification was popular among enthusiasts seeking to enhance the performance of their vehicles, and it remains a recognizable feature in the history of Ford performance engines. The availability of aftermarket manifolds further broadened the options for customization and performance tuning.
