BMW does not have that ..BMW's short block consists of an aluminum hump with absolutly not one additional part not even the dowels. they supply a box with the pistons that were fitted ( measured and matched to bore) for the technician to install. , no crank,no rods, no bearings, nothing, nada, zilch...
BMW does not have a long block per-say.. they call it an exchange engine.. head installed comes with valve cover to oil pan sans any accessories or intake/ exhaust manifold. The timing gear comes installed already..

Interesting. Thanks for the information.
Wiki: A short block is the portion of the engine block below the head gasket but above the oil pan. An in-block cam engine will also include the camshaft and timing gear. The overhead cam style of engine will not include the aforementioned parts on the shortblock. A shortblock is usually purchased to upgrade the water jacket, piston size or bore. Assemblies typically include the crankshaft installed and balanced along with the main bearing.
