Intake Manifold, AFR Magnum Series, BBC, Single Plane, Tall Deck

Chevrolet Big Block Tall Deck Magnum Single-Plane Intake by AFR®

A cast-aluminum 4500-flange manifold supports a matched high-rpm Big Block induction combination.

This AFR® Magnum 4901 manifold is designed for a tall deck Big Block Chevrolet with the matching 18-degree cylinder-head arrangement. The single-plane aluminum casting uses a 4500 carburetor flange and a 4000-8500 RPM operating range. Computer-controlled machining establishes the mounting surfaces, while additional material in the as-cast runners permits custom port matching. Port matching is a separate preparation step, not a CNC-ported finish included with this manifold.
