The "bottom end" is anything below the heads. This includes the engine block,pistons,rods, and crankshaft. Also all the support system, like main bearings, etc. A "built" bottom end usually refers to a forged, instead of cast steel, pistons, rods, and sometimes crankshaft. These parts are much stronger, and obviously able to handle greater stresses than their cast counterparts. This is a bit of oversimplification, but gives you the general idea.
