Does anybody know the difference between a “short block” and a “long block”? Just wondering because when looking at engines, I always see them advertised as one of the two. Is one like longer physically then the other? Whenever I’ve looked at motors, they all look they same. My question is based off of 350 Chevy’s.
thanks.
Long block will have the heads, short block won’t
Hmm. Makes sense, thanks.
Short block and long block are two terms like tune up, where the meaning changes with who is talking. So a big YMMV is needed here.
To be absolutely sure, ask questions.
In my experience Short block = Everything below the cylinder head gasket(s), and above the oil pan. This may or may not include the oil pump. Head Gasket(s), and pan gasket may or may not be included. (Probably not).
Depending on who you are buying from, you may get all new parts (not common), all used, a mixture of new and used, or a mixture of new used and remanufactured (most common).
Long block Everything below the valve cover(s) and above the oil pan. May include valve cover(s) and pan. Comments about new, used and reman also apply to long block.
Parts not usually included in a long block include manifolds, flywheel/ flexplate, electrical wiring, sensors, carb, or injectors, alternators, power steering pump A/C compressor, and various belt drives, etc.
Water pumps can go either way. Some times it will be included it as it may be part of the cam drive, or they want to cut down on comebacks due to poor performance of the old water pump.
