The Performer RPM Air-Gap Intake Manifold by Edelbrock is designed for high-performance rectangular-port big block cylinder heads.
The RPM air-gap incorporates race-winning technology that has been used in the Victor Series intakes.
The open air space separates the runners from hot engine oil, resulting in a cooler air/fuel mixture for a denser charge and more power.
It includes two distributor clamp locations, rear water outlets, and nitrous bosses.
It accepts all late model A/C brackets and alternators for the street and is for square-bore carburetors only.
The manifold height is 4.45 inches in the front and 6.0 inches in the rear.
The port dimensions are 2.24 inches tall by 1.60 inches wide.
The runners are tuned to move the power band 1,000 RPM higher than Performer air-gap manifolds, from idle-5,500 RPM up to 1,500-6,500 RPM.
There is no provision for exhaust heated chokes and no exhaust crossover.
