Edelbrock part #7516 RPM Air-Gap intake manifold is based on the
powerful Performer RPM Vortec #7116. This single four-barrel intake is
designed for 262-400 c.i.d. Chevy V8's with 1996 and later Vortec (L31)
cast iron or Edelbrock E-Tec aluminum heads. 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. An external water
bypass boss is machined into the front of the water crossover for use on
1996 and later Vortec production engines. Includes rear water outlets,
nitrous bosses, a temp sensor boss that clears all waternecks, two
distributor clamp locations and a heater outlet boss that's angled for
proper fit over the valve cover. Accepts 1976 and later alternator and
air-conditioning brackets for street installations. For square-bore
carbs. No provision for exhaust-heated chokes and no exhaust crossover.
Will not fit under stock Corvette hood.
