Description

Edelbrock Part # 7581 RPM Air-Gap 351W intake manifold is designed for street and high performance 351-427 c.i.d. 351W Ford V8 applications. The RPM Air-Gap incorporates the same race-winning design that’s been used on our Victor Series competition intakes for decades. 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. Larger cross sectional area and a taller carb flange than #7181 for compatibility with large displacement, stroker 351W based engines. Includes bosses for nitrous and rear water crossover.
