SB Chevy Aluminum

BMP Small Block Chevy Aluminum Engine Blocks
Once known as the Very popular World Products Motown Lite block and now the all new redesigned and retooled block by Bill Mitchell Products is better than ever. The Bill Mitchell Products SBC Aluminum Block stands apart from all others by featuring several important features, such as stabilizing and reinforcing fins on the outside the block giving the cylinder walls more stability and enhances the cooling. There are also reinforcing ribs in the valley that connect the left and right banks that add the needed strength in the center of the block. The ribs are drilled to cross-feed the lifter as well. What’s more, the block is configured for priority main oiling to assure that the crankshaft is lubricated before the lifters. Standard fuel pump location and engine mounts for a drop in replacement.
