This new manifold for Big Block Chevys is a worthy companion to our phenomenally successful single plane small block racing manifold. Designed for serious performance big block applications, it features nitrous bosses, dual distributor holddowns, four corner water ports, and is intended for rectangular port cylinder heads. Runner size is effective for 468 to 540 cid engines. Use Fel-Pro intake gaskets #1275. Use an 800 cfm or larger 4150 square bore carburetor.

Note: These manifolds are not legal for sale or use on any pollution-controlled motor vehicles.
