engine run stand question(help)

^^^ yes, I saw it recently It was just a piece of 3/8 plate holding the starter where it should be and a flywheel. Im sure an empty convertor could work the same. Im gonna mount the whole engine/904 to my test stand and just put a loop on the trans cooler line and a Bayer aspirin bottle in the output shaft seal.

Seems I remember some company makin an adapter for the starter so you could just bolt it on the block? I tried to find it with no success. If you had a busted bellhousing, you could use that and just cut that piece off.
