Small Block Chevy Vortec, 1500-6500 rpm

ED75163

75163

Based on the powerful Performer RPM Vortec #ED7116, this single four-barrel intake is designed for 262-400 Chevy V8 with 1996 and later Vortec (L31) cast iron or the new Edelbrock E-Tec aluminium heads. The RPM Air-Gap manifold delivers outstanding performance using the same air-gap technology found in our race-winning Victor manifolds. This unique design separates the hot engine valley from the air/fuel mixture for a cooler, denser charge and more power throughout the rpm range. 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 ir-conditioning brackets for street installations. No provision for exhaust-heated chokes and no Powder Coated exhaust crossover. Will not fit under stock Corvette hood. Black Finish. Made in USA
