Edelbrock RPM Air-Gap Intake Manifold for Mustangs with 351W Engines.
Designed for street and high performance 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. A larger cross sectional area and a taller carb flange than EDL7181 offer compatibility with large displacement, stroker 351W based engines.
Air-Gap manifolds are ideal for street performance from idle-to-5500 rpm.
Features 'As-Cast' finish. Made in the USA. 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 bracket SRK4000.
