Fits standard 23 degree heads, early to 1986 applications. Later years require manifold modification.
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.
Note: Comes polished by default. Satin finish (cast only) and black hard anodizing is available at an extra charge
