Aluminum SBC

BMP Small Block Chevy Aluminum Engine Blocks 

From any angle this aluminum block is the class of the SBC field. Enhanced cooling, Strengthening ribs & more make this the best value on the market. The BMP SBC aluminum block stands apart from all others. The unique strengthening ribs serve several important functions, such as stabilizing and reinforcing the cylinder walls and enhancing cooling. They look cool too! There are also reinforcing ribs in the lifter valley that connect the two banks. These ribs are also drilled to cross feed the lifters. What's more, the block is configured for priority main oiling to assure that the crank gets oiled first.
