Product Details

The Edelbrock 7520 RPM Air-Gap Dual-Quad intake manifold is engineered for street performance on 396-502 cubic inch Big Block Chevy V8 engines equipped with 1975 and earlier oval port cylinder heads. This dual-quad manifold delivers exceptional performance gains in the 1500-6500 RPM range, making it ideal for street and street/strip applications.

Air-Gap Technology:

Features Edelbrock's innovative Air-Gap design that incorporates an open spacer beneath the intake plenum. This design isolates the intake runners from the heat of the engine valley, keeping the air/fuel mixture significantly cooler and denser for improved power and throttle response throughout the RPM range.

Key Specifications:

  • Application: Big Block Chevy 396-502 cubic inch V8 engines
  • Cylinder Head Compatibility: 1975 and earlier oval port heads
  • Power Range: 1500-6500 RPM
  • Height: Stands 7/8" taller than the low-profile C-66-O dual-quad intake
  • Carburetor Configuration: Dual-quad setup
  • Large runner design optimized for improved airflow

This intake manifold is an excellent choice for enthusiasts seeking to maximize the potential of their Big Block Chevy engine with a classic dual-quad carburetor setup. The Air-Gap design provides measurable performance improvements over traditional intake manifolds by maintaining cooler intake temperatures and optimizing air/fuel distribution across all cylinders.
