Summit Racing GM LS 6.0L Iron Block

A performance-prepped iron block capable of supporting over 1,400 horsepower.

It's no secret GM's LS engines have incredible potential. But once you start bolting on big superchargers or turbos, a factory aluminum block just can't contain the power. Fortunately, GM made 6.0L cast iron blocks that are plenty strong--and Summit Racing Equipment now offers a performance-prepped version that is rated to over 1,400 horsepower.

The seasoned block features a finished 4.030" bore and a 9.240" high deck, six-bolt main caps, and a one-piece rear main seal. The cam bearings and freeze plugs are included too.

The Summit Racing 6.0L block is clearanced for stroker cranks up to 4.000" stroke with H-beam style connecting rods.

OTHER STUFF WORTH KNOWING: Summit Racing has all the internal parts and external goodies needed to bolt to the 6.0L block--mild or wild, it's your choice.
