BBC Performer RPM A/G Manifold- R/P - 396-502

The BBC Performer RPM A/G Manifold from Edelbrock is purpose-built for big-block Chevrolet engines ranging from 396 to 502 cubic inches, making it an essential upgrade for serious performance enthusiasts and engine builders. This aluminum intake manifold is engineered to maximize airflow efficiency while maintaining streetable characteristics, ideal for both naturally aspirated and supercharged applications. Whether you're building a restoration project, a street machine, or preparing a competition engine, this manifold delivers the breathing capability modern BBC power plants demand.

Edelbrock's Performer RPM design utilizes advanced port matching and optimized runner geometry to promote laminar fuel distribution and velocity, reducing turbulence and enhancing combustion efficiency across the RPM band. The casting features robust internal passages that minimize restrictions while the aluminum construction provides excellent thermal stability and weight savings compared to cast-iron alternatives. The A/G designation indicates this manifold accepts both air gap and gasket-matched configurations, offering flexibility for various engine bay layouts and cooling strategies. At 21.33 pounds, it represents a meaningful weight reduction that improves overall vehicle dynamics and reduces parasitic engine load.

This manifold is compatible with 396, 427, and 502 big-block Chevrolet engines and works seamlessly with standard BBC mounting patterns and carbureted or fuel-injected cylinder heads. Installation requires proper gasket selection and surface preparation to ensure leak-free sealing, and the compact footprint fits most traditional BBC engine bays without major modifications. Experienced mechanics and engine builders rely on Edelbrock's proven track record for durability and performance consistency, making this manifold a trusted choice for rebuilds, restorations, and high-output street and strip applications.
