ALL  MANIFOLD - Part Number 75621
Manifold Polished RPM Air-Gap 2-R, non-EGR. Chevy BB. 1500-6500 rpm. Designed for street 396-502 c.i.d. Chevrolet V8s with high-performance rectangular-port 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 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. Carburetor Recommendations: Edelbrock Thunder Series AVS or Performer Series carb, 650-800 cfm use bracket #8031 for 1972-76. Installation Notes: Recommended intake gasket: Edelbrock #7203. Manifold height: A-4.45 in, B-6.0 in. Port exit dimensions: 1.60 in x 1.94 in. Not legal for sale or use on pollution controlled motor vehicles.
