BBC Performer RPM A/G Manifold- R/P- Polished

The BBC Performer RPM A/G Manifold from Edelbrock is purpose-built for serious big-block Chevy engine builders and street/strip enthusiasts who demand peak intake port velocity and cylinder filling efficiency. This aluminum manifold replaces restrictive factory castings and obsolete designs, unlocking horsepower across the RPM band while maintaining reliability in high-performance applications.

Engineered with Edelbrock's proven Performer RPM design, this manifold features optimized runner geometry and plenum volume that maximize air/fuel mixture distribution to all eight cylinders without dead zones or fuel separation. The polished aluminum construction offers superior heat dissipation compared to cast iron, reducing charge temperature and improving combustion efficiency—critical for extracting consistent power and preventing detonation under load.

Weighing 21.32 pounds and measuring 14.9" × 7.8" × 24.05", the compact footprint fits tight engine bays while the precision-machined runners ensure proper carburetor or fuel-injection mounting surfaces. Edelbrock's quality control and flow-bench validation mean you're getting a manifold that performs as advertised, making it an excellent choice for both street and race applications.
