I once made a stand for a MGB motor by making a box exactly the size of the oil pan flange. All you need is 1 each 2" X 12" board, some appropriately sized screws, a saw, and screwdriver or even better, a drill. Measure the outside circumference of the oil pan and build a box. The footprint of the stand will be whatever the size of the oil pan is. Before you say it sounds tipsy, it was actually pretty sturdy. You could also make the front and back sides slightly longer for stability if you're worried about it.
