Although the photo in my post shows a stripped engine, the engine was mounted on the stand while it was being disassembled. The two threaded holes in the side of the block are enough to support the assembled short block (no manifolds, starter, generator, head, etc. but including the flywheel housing, flywheel, clutch assembly, and pan). Not having the pins in the holes for the bolts for the pan means that the pan can be installed while the engine is on the stand. It also means you don't have to buy the adapter.
