BBC Performer Manifold - 396-502

The BBC Performer Manifold – 396-502 is a high-flow intake manifold designed specifically for big-block Chevrolet engines ranging from 396 to 502 cubic inches. This manifold is an essential upgrade for engine builders and hot rod enthusiasts who are looking to enhance their vehicle's performance, particularly in terms of volumetric efficiency and throttle response.

Engineered with optimized runner geometry, this manifold improves air velocity and fuel atomization while minimizing turbulence that can detract from horsepower. Its cast construction ensures durability and thermal stability, making it suitable for sustained high-load conditions. The internal passages are meticulously designed to balance low-RPM torque with high-RPM breathing capability.

Ideal for applications in Chevelle, Corvette, Camaro, and truck platforms, this manifold is compatible with both carburetor and EFI setups. Proper installation requires careful selection of carburetor or EFI adapters and meticulous gasket sealing to avoid vacuum leaks, which could undermine performance gains.
