The LS engine design has incredible potential, but once you start bolting on big superchargers, an aluminum block just can't contain all that power. These Summit® iron LS blocks have all of the same potential, but their cast iron construction is capable of withstanding high-horsepower applications. These seasoned blocks feature a finished 4.030 in. bore and a 9.240 in. high deck. They also feature 6-bolt main caps and a 1-piece rear main seal, and include cam bearings and freeze plugs.
