EDELBROCK PERFORMER RPM AIR-GAP INTAKE MANIFOLD SMALL BLOCK CHEV

The Edelbrock Performer RPM Air-Gap 7501 carbureted intake manifold for small block Chevy V8 engines features improved technology and design that keeps the air/fuel mixture cooler all the way to the cylinder heads. Borrowing from the Edelbrock Victor series, the open air space from the Air-Gap design separates the runners from the heat of the lifter-valley cover. The runners are tuned to move the power band 1,000 rpm higher over the original Performer Air-Gap manifolds-from idle-5,500 rpm up to 1,500-6,500 rpm. Notes: Nitrous bosses, rear water outlets, two distributor clamp locations. Temperature sending unit boss clears all water necks. No provision for exhaust-heated chokes. No exhaust crossover.
