Edelbrock 75614 RPM Air-Gap 2-O B/B Chevy Intake Manifold
Chevy Big Block V8, Dual Plane Intake Manifold Type, One Carburetor Quantity, Endurashine
Designed for street 396-502 c.i.d. Chevy V8s (1500-6500 rpm) with large oval-port cylinder heads (1975 and earlier), the RPM Air-Gap incorporates the same race-winning technology that's been used in the 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. Includes rear water outlets, two distributor clamp locations and nitrous bosses.

- For square bore carburetors only
- No provision for exhaust heated chokes and no exhaust crossover
- Will not fit under stock hood of Corvette, 1965-67 Chevelle or 1967-81 Camaro
