Ford 429/460 V8
RPM AIR-GAP 460 (1500-6500 rpm)
Designed for street and high performance 429-460+ c.i.d. Ford V8s with standard or Cobra Jet heads, the RPM Air-Gap 460 incorporates the same race-winning design that's been used on our Victor Series competition intakes for years. The air-gap 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) and a taller carb flange than Performer RPM 460 manifold #7166 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.
