Poulan 576412805  SHORT BLOCK K970

The Short Block is a pre-assembled component of an engine, including an engine block, crankshaft, and connecting rods. The short block is part a series of options for engine repairs featuring increasingly more components of the engine: the long block (more complete, includes the cylinder block and associated parts), and then the complete engine replacement. Short blocks are a useful package for your engine repair if the parts provided in question are the extent of the damage to your engine.
