Shortblock- block, pistons, rods, crank, rings, bearings, rear main seal and plate depending on company
Longblock- shortblock, heads, cams, timing set, oil pump
Difference between a smallblock and a big block is the amount of space between the bores. But an easy rule of thumb is any thing that comes from the factory bigger then 5.9L (360ci) is a big block.

RE: whats the difference
[:@]yes damn I forgot.
The size of the distance between the cylinder bores has led to a distinction between the V8 engine families the Detroit Big Three automakers (ford, gm, and dc) have been building since the 1950s: There are Small-block and Big-block engines. These families differ in respect to the distance between cylinder bores, but not necessarily inengine displacmentsince the latter is defined by bore and stroke.
While the big-blocks have been less commonly used in recent years, the small-block families have grown in displacement and have now reached a level that was reserved for big-blocks in previous years (up to 7 litres of displacement in a Corvette). Even though the technology has greatly changed, basic specifications have been the same for fifty years
I googled too late

RE: whats the difference
Chevy also made a 400 CID small block years ago. I believe there's been other examples as well, so it's not a safe bet to base it on much of anything besides what the particular company wants to call it.
