They are fairly cheap fit any engine and are sellable very easy to the next guy. We run them all on this same stand. If you build one for your engine it will be hard to sell to someone that needs it for a different engine.
Some Diesels we start on the ground or table.you just have to hold them.

The big Diesels we hold with the skid loader or excavator.
We just bought 2 small blocks and My son straddled the trans . We fired them up in the driveway , the manifolds burned his shoe laces off.
Buy a stand and the resell it. That is what many do.Post it and in one day its gone.
