1012W— The 1012 is a splay cap stock bore space BBC based block. This block is similar to our 1005 series block. The block features a 10.2" deck height , +.400" cam, and a wide pan rail. This is a great block for 632 cubic inch motors as the tall cam allows the use of big cam cores. Larger cam cores make more power and have a more stable valve train.
