DESCRIPTION
A short block kit, identified by part number 4991101, is an assembly of engine components that includes the cylinder block, crankshaft, connecting rods, and pistons. This kit is designed to replace the lower half of an engine and is typically used in situations where the upper portion of the engine is in good working order but the lower portion has suffered damage or wear. The short block kit provides a cost-effective solution for rebuilding an engine by allowing for reuse of existing cylinder heads and other upper-engine components. It also allows for customization with aftermarket parts to achieve desired performance levels.
