Designed for 1955-86 262-400 Small Block Chevrolet
The award-winning RPM Air-Gap 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.
NASCAR Edition RPM Air-Gap manifolds will set you apart from the crowd with their durable and distinctive black powder coated finish and attractive full colour emblem.
Includes rear water outlets, two distributor clamp locations and nitrous bosses.
Accepts all 1976 and later alternator and A/C brackets for the street.
Heater outlet boss is angled for proper fit over the valve cover.
Temp sensor boss clears all waternecks.
No provision for exhaust-heated chokes and no exhaust crossover.
