BBC Performer Manifold - 396-502

The BBC Performer Manifold – 396-502 is a high-flow intake manifold engineered for big-block Chevrolet engines ranging from 396 to 502 cubic inches. This manifold represents a critical upgrade for serious engine builders and hot rod enthusiasts seeking improved volumetric efficiency and throttle response. Whether you're building a street performer or preparing for weekend track duty, this manifold eliminates the restrictive OEM design and allows your BBC to breathe at full potential across the RPM range.

The Performer design utilizes optimized runner geometry and port matching to maximize air velocity and fuel atomization without creating turbulence that robs horsepower. Cast construction provides durability and thermal stability under sustained high-load conditions, while the manifold's internal passages are precisely engineered to balance low-RPM torque with high-RPM breathing capability. The 15.2 x 7.55 x 24.2-inch footprint integrates cleanly into most BBC engine bay configurations, and the 20.08-pound weight keeps overall engine mass reasonable without sacrificing structural integrity or heat dissipation characteristics.

This manifold is ideal for 396, 427, and 502 big-block Chevrolet applications across Chevelle, Corvette, Camaro, and truck platforms. Installation requires proper carburetor or EFI adapter selection and careful gasket sealing to prevent vacuum leaks that would negate performance gains. Pairing the BBC Performer Manifold with quality fuel delivery, ignition tuning, and header work delivers tangible improvements in acceleration, mid-range power, and overall engine responsiveness that serious builders expect from a genuine Performer-series component.
