Edelbrock Ford 351 W Dual Quad Air Gap Manifold

If you're looking to get the most out of your 1969-1997 Ford 351 Windsor small-block engine, especially for street performance applications, this Edelbrock Performer RPM Air-Gap Dual-Quad intake manifold is a solid choice. It's designed to work with dual four-barrel carburetors, giving you the potential for significant power gains across a broad rpm range, specifically from 1500 up to 6500 rpm.

What sets this manifold apart is Edelbrock's unique Air-Gap design. Instead of sitting directly in the hot engine valley, the intake runners are separated by an air space. This cooler air gap helps to keep the incoming air-fuel mixture denser, which translates directly into more horsepower and torque. The large runners are optimized for airflow, and the manifold includes bosses for a rear water crossover, making it adaptable for various cooling setups. The distance between the carburetor mounting centers is 6-7/16 inches, a standard measurement for dual-quad setups.

This manifold fits a wide variety of Ford vehicles from the late 60s through the late 80s, including popular models like the Bronco, F-150, and E-Series vans, as well as many Ford passenger cars. For those running a dual-quad setup, Edelbrock offers a Progressive Throttle Linkage Kit (PN 7094) that can be purchased separately to ensure smooth and synchronized throttle operation between the two carburetors. Please note that this manifold is not CARB approved and cannot be shipped to California.
