Edelbrock RPM Air-Gap Small Block Ford 351W Intake Manifold - Black Plasma Finish

Edelbrock part #7581-BP 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 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 has a 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 a rear water crossover. Edelbrock carbs will work with Ford automatic overdrive trans (AOD) when used with Lokar bracket SRK-4000. Core products are engineered, manufactured, and tested in the USA to ensure the best quality possible.
