Weiand Stealth Intake Manifold for Big Block Chevy – Compatible with 396 to 502 CID Oval Port Heads, 9.8″ Deck Height, Optimized for Smooth Idle Through 6800 RPM

Description

The Weiand Stealth (PN 8019) is built for Big Block Chevy 396–502 engines with oval port heads and a 9.8″ deck height. Designed to outperform traditional dual-planes, the Stealth delivers broad power from idle to 6,800 RPM, making it a proven choice for street/strip builds, bracket racers, and high-performance muscle cars.

With a high-rise dual-plane design, the Stealth provides strong mid-range torque while carrying horsepower up top. Constructed from lightweight cast aluminum, it reduces weight versus factory iron intakes while improving airflow and cooling efficiency.

If you’re running an oval-port BBC up to 502 CID, the Stealth is a bolt-on solution that combines drivability with track-ready performance.
