Long block

Long block

Long block is an automotive term describing an engine sub-assembly consisting of the following:
* Short block. The long block is always a superset of the corresponding short block.
* Cylinder head. A complete new or remanufactured cylinder head assembly is installed with a new head gasket and torqued to specification. Complete cylinder heads include new or reconditioned valves, valve springs, valve guides (if applicable), valve seats (if applicable), valve locks, and valve keepers. The bare head is free from cracks, warps, or holes.
* If the engine is a flathead, then the valve train is installed if the short block did not already have it.

On most engines, the camshaft will be installed. On many engines with timing gears, the camshaft will be timed.A Long block engine replacement will typically require swapping out parts from the original engine to the long block.These parts include the intake manifold, the exhaust manifold, Alternator, Power steering pump, if any, and Air conditioner compressor, if any are installed in the vehicle.
