Edelbrock Part # 75011 RPM Air-Gap RPM intake manifold is 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. Edelbrock’s Performer RPM gives you the ultimate in street high-performance. Accepts all 1976 and later alternator and A/C brackets for the street. 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 hood. This manifold offers a polished finish for a brilliant shine and classic look.

Sealant must be used on intake bolt threads if the threads extend into lifter valley or coolant passage.
NPT/Pipe thread fittings require the use of Teflon tape or paste on threads to ensure proper seal.

Hardened washers Must be used with intake bolts to ensure proper torque and prevent galling of the aluminum.
