Edelbrock 75163 Performer RPM Air-Gap Intake Manifold Small Block Chevy Vortec Black

The Edelbrock 75163 Performer RPM Air-Gap intake manifold is engineered for 262-400 cubic inch small block Chevy V8 engines equipped with 1996 and later Vortec (L31) cast iron cylinder heads or Edelbrock E-Tec aluminum heads. This high-performance intake manifold builds upon the proven Performer RPM Vortec #7116 design with advanced air-gap technology.

Air-Gap Technology:

The innovative air-gap design features an open air space that isolates the intake runners from the hot engine oil in the lifter valley. This separation keeps the air/fuel mixture significantly cooler and denser, resulting in increased horsepower and torque throughout the RPM range.

Key Features:

• Designed for square-bore carburetors
• External water bypass boss machined into front water crossover for 1996+ Vortec engines
• Rear water outlets included for proper cooling circuit
• Nitrous bosses for power adder applications
• Temperature sensor boss positioned to clear all water necks
• Two distributor clamp locations for installation flexibility
• Angled heater outlet boss for proper valve cover clearance
• Compatible with 1976 and later alternator and air conditioning brackets
• Durable black powder-coated finish for corrosion protection and distinctive appearance

Important Notes:

• No provision for exhaust-heated chokes
• No exhaust crossover passages
• Will not fit under stock Corvette hood due to increased height
• Recommended for street/strip and high-performance street applications

This intake manifold delivers excellent performance gains across the power band, making it an ideal upgrade for Vortec-headed small block Chevy engines in street rods, muscle cars, and performance trucks.
