 Product Description

The unique World Products Motown LS SBC block lets you utilize a full compliment of standard small block Chevy components with the  decided advantage of being able to employ high flowing LS-type cylinder heads. In addition to the internal components, the  World Products Motown LS allows use of expensive already-purchased Small Block Chevy items like pulley kits and external accessories. The block also boasts a coolant capacity in excess of 150 fluid ounces  to provide superior cooling.

THE WORLD PRODUCTS MOTOWN LS IS A UNIQUE ONE-OF-A-KIND BLOCK MADE ONLY BY WORLD PRODUCTS!

Note: When using LS-style heads on the Motown LS you must use an adapter on the heads to facilitate a return flow to the  radiator. The World Products Cooling Adapter also accommodates standard SBC  accessory brackets.

The latest design World Products Motown LS small block Chevy Hybrid engine block features a camshaft location which has been raised in the block by +.134". The block now comes standard with a 55mm cam tunnel and cam cores are now readily available from Erson Cams at an affordable cost for this application. This design allows the use of both I-beam and H-beam connecting rods with a 4" stroke crankshaft, and the large diameter cam core provides for exceptional valve train stability at high RPM operation. Bushed lifter bores are standard with a choice of .842" or .904" inner diameters. The Motown LS can be built with a carburetor or EFI induction. Deck height is a standard LS 9.240". The special cylinder head and intake manifold adapter allows the use of a std distributor as a small block Chevy.
