World Products has introduced an innovative engine block that utilizes standard small block Chevy internal components and ignition, but allows the use of the superior flowing LS-series cylinder heads and intake manifold. The cast iron block employs a standard small block Chevy water flow path, with expanded water jackets holding 152 fluid ounces of coolant per side (almost a 1/2-gallon more than the OEM block). World also offers special adapters for LS cylinder heads that facilitate a return flow of coolant to the radiator and accommodate standard SBC accessory brackets.

The “Motown LS” block is ideally suited to enthusiasts who have invested in small block Chevy components—including pulley systems—and seek an economical means of upgrading to the newer LS-series cylinder head technology.

A “Sportsman” series block is available with nodular iron splayed 4-bolt mains, while a “Race” block has 1045 steel billet caps.
Both have a 9.240" deck, 400 mains, and a 4.115" bore. A priority main oiling system assures optimum lubrication. Builders must use pistons compatible with the LS heads, and a special SBC camshaft that has lobes positioned properly for the LS valve train.
