The 1010 block is a billet aluminum replacement for the Big Block Chevrolet Bowtie block. The block features stock bore spacing, stock cam height, and is offered in 9.8” or 10.2” deck heights. This is the only block for racers that desire the ultimate in strength, power, and weight savings. The 1012 and 1016 are splay cap stock bore space BBC based blocks. These blocks are similar to our 1005 and 1007 series blocks. The 1012 features a +.400” high cam and a wide pan rail. The 1016 features a +.600” high cam and a wide pan rail. These are great blocks for over 600 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.
