Home built flow benches

Until about 25 or so years ago My Uncle and cousins owned and ran a machine shop in Chicago, Mid West Crankshaft. One of my cousins moved here and brought with him a home built flow bench. The story is that a guy in Chicago ran a Hemi powered fuel dragster and built the bench so he could do his own heads. He's tried to sell it to me a couple times but I don't need it. Cool piece though.
