Short blocks are generally the block, crank, rods, pistons, bearings, rings, oil pump/pick up (depending on the engine), freeze plugs cam bearings and camshaft assembled.
Long blocks are the same except the lifters, pushrods and fully assembled heads are included. Everything else is concidered bolt on or externals.
Do you mean big and small block?
Also cams generally arnt done as its an engine out job, and will make more of a difference (and I understand a reduced engine life) on a smalled capacity engine.
