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

The BBC Performer RPM A/G Manifold O/P 396-502 is a high-performance air-gap intake manifold specifically engineered for big block Chevy engines with displacements ranging from 396 to 502 cubic inches. Designed by Edelbrock, a leader in intake manifold technology, this manifold is ideal for street, strip, and performance applications.

The air-gap design creates a sealed chamber beneath the manifold runner floor, isolating intake charge temperatures from engine block heat and reducing fuel vaporization. This thermal separation allows cooler, denser air charge to enter the combustion chamber, improving volumetric efficiency and combustion quality across the RPM band. The Performer RPM's carefully ported runners and optimized plenum design promote smooth, even fuel distribution to all cylinders.

This manifold is perfect for big block Chevy builders who prioritize mid-range responsiveness and peak power without sacrificing streetability or reliability. Its cast aluminum construction provides lightweight durability, making it a direct bolt-on upgrade that transforms how your engine breathes.
