Q: While looking for a remanufactured engine for my car I came across the terms short and long block. What is the difference?
A: In general, a short block is a remanufactured engine usually only consisting of the engine block, crankshaft, pistons, and sometimes the camshaft and timing chain (on non overhead camshaft engines). All the other components, including the cylinder head(s) and manifolds, will need to be used from your existing engine or need to be purchased. A long block also includes the cylinder head(s). The exact components will vary depending on the engine and remanufacturer. Have a qualified technician determine the usability of engine components that will not be replaced. When obtaining quotes, have the engine manufacturer specify all the components that are part of their short or long block.
