??? How do you figure that ???

Anyhow, many years ago I built something like this out of 2x4's and plywood. I built a "box" that the oil pan sat in and then attached 24" 2x4's across the front and back to mount casters and stabilize the unit. It didn't need to be any bigger than the engine since the engine weighs so much more than everything else.
