Chevrolet 262–400 Small-Block Vortec/L31 Street Warrior Intake Manifold by Weiand®

Dual-plane aluminum intake fits L31/Vortec-pattern cylinder heads with a square-bore carburetor.

This Weiand® Street Warrior aluminum intake manifold is designed for Chevrolet 262–400-cubic-inch small-block V8 engines equipped with 1996–2002 L31 Vortec-style cylinder heads. Its dual-plane runners are intended for idle-to-5,500-rpm street performance. The carburetor pad accepts a square-bore four-barrel carburetor, and the manifold uses the Vortec cylinder-head intake bolt and port arrangement instead of the earlier small-block pattern. It is a Non-EGR design.
