Chevrolet 396–502 Big-Block Stealth Dual-Plane Intake Manifold, Oval Port, by Weiand®

High-rise aluminum intake for performance oval heads; 4150 square-bore carb flange.

This Weiand® Stealth aluminum intake manifold is designed for 396–502-cubic-inch Chevrolet big-block V8s with performance oval cylinder-head ports. The high-rise dual-plane runner arrangement supports broad street/strip performance over an operating range of idle–6,500 rpm. A 4150-style square-bore four-barrel carburetor mounts at the top of the manifold. Port openings measure 1.84 x 1.64 inches (height x width). The manifold measures 4.75 inches high at the front and 5.75 inches at the rear. Weiand casts and machines this Nostalgia Series manifold in the United States using original tooling; slight casting-surface variation is characteristic of the process.
