Product details:

non/EGR 262ci-400ci, 1955-1986 Cylinder Heads;
The Weiand Street Warrior is designed for use on stock or stroker combinations that feature efficient cylinder heads. The latest advances in cam design necessitated the design of a new intake manifold, and the Weiand Street Warrior manifolds fill that void. They are designed with computational fluid dynamics (CFD) software for optimized and consistent flow on every single manifold.;
