Engine run stand

[5spd540]

Anyone have one of these they built. I am looking to sell off a bunch of engines that was in my dads shop when he passed away last October. Want to make sure they will run before I sell them. Don’t want to sell a bad engine. They all supposedly good engines.let me know if you have any pics of what you have or have built.

I have not built one, but found this with a google search.

That's nice. Bet that could be made on something like a jet-ski trailer too, make it easy to transport and let a pro tuner get his fingers on it at his shop.
