Performer RPM Air Gap Small Block Ford 351W Windsor Intake Manifold 9.5" Deck dual plane

EDELBROCK 7581

PERFORMER RPM AIR-GAP 351W INTAKE MANIFOLD

The Edelbrock 7581 RPM Air Gap is designed for the street and high performance 351 -427 cubes Windsor V8 (9.5" Deck)

The Performer RPM Air-Gap incorporates the same race winning design that has been used on the Victor Series Competiton intakes. The Edelbrock Air Gap design features and open space that separates the runners from the hot enigne oil, resulting in cooler, denser air charge for more power and torque. The Edelbrock dual plane manifold has a larger cross sectional area that the other models, this makes the 7581 Air Gap compatible with the large displacement stroker 351W based engines.

The 7581 manifold also includes bosses for Nitrous and rear water crossover. The Edelbrcok carbs will work with ford Automatic Overdrive trans (AOS) when used with a LOKAR Bracket SRK-4000.
