Sure thing Bruce, for support I'm putting some wood blocks on the floor and using two jackstands where the bottoms of the old mounts will sit, I mocked it up to make sure the stands have a solid spot to hold the engine up without slipping off.
I think I would want something a tad more solid than that. Vibration and all. You'll have your hands full breaking it in, let alone chasing it around the garage, lol.
Some sort of cheap home engine cradle fashioned out of wood should suffice, with the ability to lash it down via the mount areas on both sides.
