Splay Cap BBC
The splay cap block is very popular among Pro Stock and nitrous Pro Modified racers. The splay cap block is a design similar to stock GM block, the pan rail is slightly raised above cap face. The outer cap bolts are at an angle and reach a very strong area of the block above the pan rail. This design has proven to be very strong and reliable. The design allows motor builders to take advantage of new oil control technology.
