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.
