Slick engine run stand

When I built my start stand, I built it as low as I could to the ground.
With an engine running, it will take off across the garage floor unless I put some 4x4's under it on cinder blocks.
It has all the electrics, radiator, fuel cell and gauges off in this pic, because I was putting it into the barn up at my farm, the mice would have had a field day with the wiring.
Here is a pic with it functional, minus the mufflers.

Wow. Nice work. I like that too for a more professional unit, if time is on your side. ;)
