Description

Designed for 1955-86 262-400 c.i.d. Chevrolet V8’s, the award-winning RPM Air-Gap intake manifold incorporates the same race-winning technology that’s used on our Victor Series competition intakes. 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. Accepts all 1976 and later alternator and A/C brackets for the street. The heater outlet boss is angled for proper fit over the valve cover. The temp sensor boss clears all waternecks. For square-bore carburetors only. No provision for exhaust- heated chokes and no exhaust crossover. Not for 1987 and later cast iron heads and will not fit under stock Corvette hoods.
