Edelbrock 75624 RPM Air-Gap 2-R Intake Manifold- $385.95

Chevrolet 396-502 V8
RPM AIR-GAP 2-R (1500-6500 rpm)
Designed for street 396-502 c.i.d. Chevrolet V8s with high-performance rectangularport heads, the new RPM Air-Gap incorporates the race-winning technology that's been used on our Victor Series intakes. The open air space separates the runners from the hot engine oil, and as a result, the air/fuel mixture stays cooler for a denser charge and more power. Includes rear water outlets, two distributor clamp locations and nitrous bosses. Accepts all late model alternator and A/C brackets for the street. 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.
