I have my 261 on a rotating stand sideways. I don't have the bell housing on so I am using 2 bell housing bolts and 2 bolt holes on the side-mount holes. I have not figured out the new picture posting protocol (it took me a LONG time to figure out the last one) but I would be happy to take a picture of my engine on the stand and email it to you, if you like.
All the big diesel engines (JD, CAT, Cummins, ect) mount their engines in a stand on their sides UNLESS there is some method of supporting the end of the engine.
