MOTOWN LS (Hybrid)

The Motown LS block allows the use of high flowing LS style cylinder heads with affordable SBC rotating assemblies and related components. The camshaft location has been raised in the block by +.134” and the block now comes standard with a 55mm cam tunnel. This design allows clearance for the use of a 4.000” stroke crankshaft, and the large cam core provides for exceptional valve train stability at high RPM operation. Bushed lifter bores are standard with a choice of .842” or .904” diameter. The Motown LS can be built with carburetor or EFI induction and distributor or crank trigger ignition. A standard LS 9.240” deck height means off the shelf LS intake manifolds can be used.
