Difference Between Short Block Engine, Long Block Engine and The Turn Key Engine.
To start with all engines are the same dimensions, some people ask if a short block is smaller than a long block, the answer is no! They are the same size, the reason they call it a short block is that many of the parts are left off such as heads, rocker arms, lifters, oil pan, etc. In other words they have been shorted from a long block, hence the name short block. To help clarify the three I will give you a list of what is included in each engine.
Short blocks have the following included:
Lower block, crankshaft, connecting rods, pistons, rings, main bearings, rod bearings, cam bearings, warning only purchase this unit if you have a qualified engine specialist who can properly clean, rework, and assemble to a complete running engine, it will require numerous new parts, and lots of time not recommended for the weekend warrior !!!
Long block engines have the following included:
Block, crankshaft, pistons, rings, main bearings, rod bearings, cam bearings, camshaft, timing chain, sprockets, lifters, push rods, rocker arms, cylinder heads, oil pump, oil screen, and gasket set. This will also require a skilled engine specialist, and hours of time cleaning the following parts that you take off your old engine to reuse on your new engine, such as oil pan, timing cover, valve covers, intake manifold, carburetor, water pump distributor, all ignition components, it will require many hours of cleaning and assembly, plus if you screw it up it is your problem!!!
Turn key engines have the following included:
This is the way to go, your engine arrives ready to run right out of the box, the engine is complete from the oil pan to the air cleaner, it has been hot run tested, the engine is broken in, it has been tested for oil leaks, fuel leaks, vacuum leaks, and coolant leaks, timing, carburetor, choke, and mixture screws are all adjusted, each cylinder is balance tested to be sure it is performing at 100 %, temperature is tested at all 4 corners to be sure the block is cooling evenly, turn key engines have all new moving parts, plus brand new cylinder heads, valves, springs, retainers, lifters, push rods, rocker arms, intake manifold, new carburetor, distributor, cap, coil, rotor, spark plugs, ignition wires, new fuel pump, water pump, fuel lines, all filters.
