Ford 429 460 Intake Manifold, Dual-Plane, Performer RPM AIR-GAP.

Edelbrock 7566 RPM Air-Gap Ford Big Block 429 460 Intake Manifold

Edelbrock ED7566 RPM Air-Gap 429 460 intake manifold is designed for street and high performance 429/460+ c.i.d. Ford V8's with standard or Cobra Jet heads. The RPM Air-Gap 460 intake is a dual plane Air Gap design that's perfect for Street cruisers and tough streeters wanting that extra rpm out of a dual plane intake. The Edelbrcok Ford 460 Air-Gap intake design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. It also features a larger cross sectional area (3.3 square inches) than the Performer RPM 460 manifold #7166 intake manifold for even more power in high performance and large displacement engines. The carb mount flange accepts both square-bore and spread-bore carbs for Cobra Jet applications. Will not fit 1988 and later models. Note: Early Cobra Jets came with Quadrajets.
