I make a cradle out of 2X4's that supports the oil pan rails, and do plenty of cross bracing so it doesn't collapse sideways. You can make it tall enough to sit on the floor, but a shorter one that allows you to put the engine on a workbench makes more sense.
Just be sure you have a very sturdy workbench!
