The Edelbrock RPM Air-Gap #7501 intake manifold is designed for 1955-86 262-400 c.i.d. Chevrolet V8's, the award-winning RPM Air-Gap intake manifold incorporates the same race-winning technology that's used on our Victor Series competition intakes. 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 RPM Air-Gap #7501 intake manifold is a dual-plane, high-rise design with a 180-degree firing order to produce incredible top-end horsepower while retaining good throttle response. The larger plenum and runners match the free-flowing exhaust, high-lift cams and other modifications of a high output engine. This manifold is intended for high-performance street or competition engines that run up to 6500 rpm. Edelbrock's Performer RPM gives you the ultimate in street high-performance. Accepts all 1976 and later alternator and A/C brackets for the street. No provision for exhaust- heated chokes and no exhaust crossover. Not for 1987 and later cast iron heads and will not fit under stock Corvette hood. The Edelbrock RPM Air-Gap #7501 also features a natural aluminum finish for a classic look. For the ultimate "Made in USA" quality, every Edelbrock intake manifold is cast and machined in the USA.
