Product Details

This is the FAST 4150 Open single plane intake manifold, designed for Ford small block engines. If you're looking to get more power out of your Ford 289, 302, or 351W, this manifold is built to help you achieve significant gains in horsepower and high-RPM torque, typically in the 4500 to 8500 RPM range. It's a popular choice for performance builds where maximizing engine output is the goal.

What sets this manifold apart is its single-plane design, which helps promote better cylinder filling and scavenging at higher engine speeds compared to dual-plane designs. This particular model is set up to accept any square bore, four-barrel 4150-style throttle body, making it easy to pair with a wide variety of performance carburetors. Plus, it features a fuel injector boss in each runner, so you can easily add fuel injection if you decide to go that route, accepting FAST high-performance injectors.

This manifold fits a wide range of Ford vehicles, including many F-Series trucks, Broncos, and Econoline vans from the 1960s through the 1990s. It's a solid option for anyone rebuilding or upgrading their Ford small block for performance applications. Please note that this manifold is not CARB approved and cannot be shipped to California.
