 Product Description

The highly refined Bill Mitchell Products BMP BBC aluminum block we have incorporated a significant number of key technical features that set it apart from the competition. And because it’s been designed specifically for the drag race market and keeping the marine and street guys in mind. This and the price of the BMP Big Block Chevy makes this the only choice for your ride. Dollar for dollar, you won’t find a better value in big block Chevrolet technology. It’s manufactured to QS-9000 quality control standards. 

One easy to spot difference between the BMP BBC and others is the use of horizontal ribs. Not only do they look cool, but they also serve to improve engine cooling and reinforce the cylinder bores.
Total bottom end dependability is achieved through the use of 1045 alloy steel billet splayed 4-bolt mains (much stronger than commonly used 1020 steel) with genuine ARP main studs.
The BMP BBC Aluminum Block is compatible with all GM Gen IV components (cam location is standard) and is the best foundation for building a large displacement big block Chevrolet with total reliability. Factor in pricing that’s more than competitive, and you’ve got a winner! Formerly known as the World Products Merlin III Aluminum Block.
