ALL  MANIFOLD - Part Number 75161
Manifold Polished RPM Air-Gap Vortec non-EGR, SB Chevy 1500-6500 rpm. Based on the powerful Performer RPM Vortec #7116, this single four-barrel intake is designed for 262-400 c.i.d. Chevy V8s with 1996 and later Vortec (L31) cast iron or the new Edelbrock E-Tec aluminum 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 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. Available with standard finish, polished with PermaStar or new EnduraShine finish for a look you've got to see to believe. Carburetor Recommendations: Edelbrock Thunder Series AVS or Performer Series carb, 650-800 cfm use bracket #8032 for 1972-78. Installation Notes: Recommended intake gasket Edelbrock #7235 or GM #89017465. Manifold height: A-4.20 in, B-5.25 in. Stock brackets will require modification to fit the upright maniofld bolt holes.
