Big Block Chevy tall Manifold 4.69 inch.
To increase performance through even distribution of air and fuel to each cylinder, The Blower Shop has developed its own intake manifolds for small and big block Chevy applications. Our 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.
**Comes polished by default. Satin finish (cast only) and black hard anodizing is available at an extra charge, but are not available through online orders. Please call (208) 985-7650 to place special orders.
