RPM Air-Gap(r) 351W Manifolds non-EGR (1500-6500 rpm)

Edelbrock has several styles of aluminum intake manifolds to fit different applications. Each style of manifold has characteristics that make it ideal for the application for which it is intended. Years of design and testing in the area of induction technology have given the Edelbrock team invaluable insights into which characteristics work best under what conditions. For the ultimate in quality, every Edelbrock manifold is cast at the ultramodern Edelbrock Aluminum Foundry and machined on computerized machining centers at Edelbrock headquarters. Whether you're building a daily driver, ultra high-performance street machine or race car, an Edelbrock intake manifold will provide the power right where you want it.

Designed for street and high performance 351-400+ c.i.d. 351W Ford V8s, the RPM Air-Gap incorporates the same race-winning design that's been used on Edelbrock's 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. RPM Air-Gap manifolds are modeled after Performer RPM intakes for high performance street power from 1500-to-6500 rpm. Larger cross sectional area and a taller carb flange than 11058 for compatibility with large displacement, stroker 351W based engines. Includes nitrous bosses. No provision for exhaust heated chokes and no exhaust crossover. Aftermarket 4-bbl carbs are not compatible with Ford Auto Overdrive Transmission (AOD) unless used with Lokar bracket SRK-4000.
