FAST Intake Manifold BBC 4150 Open

FAST is a well-known name in performance fuel and ignition systems, and their single plane intake manifolds are built to help you get the most out of your engine. This particular manifold is designed for Big Block Chevrolet engines, specifically targeting the 3500 to 7500 RPM range where you'll see a significant increase in horsepower and high-RPM torque. It's a popular choice for builders looking to extract serious performance from their engines.

This single plane design features an open plenum, which helps improve airflow and allows the engine to breathe more freely at higher RPMs. It's set up to accept any standard square bore, four-barrel 4150-style throttle body, making it easy to pair with many popular carburetor setups. Plus, each runner has a built-in boss for fuel injectors, so you can easily upgrade to electronic fuel injection using FAST's high-performance injectors if you choose. This manifold fits a wide range of vehicles, including classic Chevrolet models like the Bel Air, Chevelle, and C10 pickups from the 1960s and 70s, as well as many other Chevrolet and GMC applications from that era and beyond.

When you're aiming for maximum power output, especially in the mid-to-high RPM band, a well-designed intake manifold like this one makes a big difference. It's a solid component for anyone rebuilding or modifying their Big Block Chevy for performance applications.
