I have a couple (well, maybe more than a couple) on engine stands. On the 4.0 I plan to put in a scrambler at some point, I left the engine mounts on the block and have a couple 2x4s running from the mount bolt to the center leg on the stand. Relieves a lot of the weight from those bolts. On a 258, I just have it hanging from the bolts at the rear. I probably should add some support to that one.
