Big Block Chevy Street/Marine Manifold is machined from an aluminum casting utilizing integral solid sides. This allows us to increase the level of strength and overall rigidity of the manifold. We use a slight radius on the floor for increased runner length and optimal airflow.

Machined for water this manifold will accept any standard thermostat and Chevy housing and is designed to work with 6-71 though 14-71 superchargers.
