Engine - Intake Manifolds - Cast Iron High Rise Manifold

From GM Performance - This manifold is a cast iron version of the aluminum Z-28 intake manifold. It offers the breathing benefits of a high-rise intake manifold in a less expensive package. It is recommended for Chevy enthusiasts on a budget, and for racers competing in classes which require a cast iron intake manifold. It is also suited to marine applications because cast iron is less susceptible to corrosion damage than aluminum. Technical Notes: The carburetor mounting pad accepts both standard flange and spread-bore four barrel carburetors. This manifold is identified by orange paint on the Bow Tie.
