Edelbrock 75013 Performer RPM Air-Gap Small Block Chevy Intake Manifold

The Edelbrock Performer RPM Air-Gap intake manifold is engineered for 1955-86 Small Block Chevrolet V8 engines with 262-400 cubic inch displacement. This high-performance manifold incorporates race-proven Air-Gap technology that delivers measurable power gains through innovative thermal management.

Air-Gap Technology:

The signature Air-Gap design features an open air space separating the intake runners from the lifter valley, isolating them from hot engine oil. This thermal barrier keeps the air/fuel mixture significantly cooler and denser as it enters the combustion chamber, resulting in improved volumetric efficiency and increased horsepower throughout the RPM range.

Key Features:

• Designed specifically for 262-400 c.i.d. Small Block Chevy V8 engines (1955-1986)
• Race-winning Air-Gap design isolates runners from engine heat for cooler, denser intake charge
• Durable black powder-coated finish provides corrosion protection and a distinctive appearance
• Compatible with all 1976 and later alternator and air conditioning brackets
• Ideal for street high-performance and street/strip applications
• Optimized runner design for broad power band with emphasis on mid to upper RPM range

Important Compatibility Notes:

• No provision for exhaust-heated chokes
• No exhaust crossover passages
• Not compatible with 1987 and later cast iron cylinder heads
• Will not fit under stock Corvette hood due to increased height
• Requires carburetor with square-bore flange pattern

This manifold represents the ultimate street performance upgrade for Small Block Chevy enthusiasts seeking maximum power gains with excellent drivability characteristics. The RPM Air-Gap design has earned multiple industry awards and continues to be a benchmark for high-performance street intake manifolds.
