Description Designed for street and high performance 351-400+ c.i.d. 351-W Ford V8s, the new RPM Air-Gap 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. The P/N 7581 offers larger cross sectional area and a taller carb flange than P/N 7181 for compatibility with large displacement, stroker 351-W based engines. Includes nitrous bosses.
