Is the experimental slant six with four rings an urban legend - or did I get the real story?

Yeah, I think there was a little icing on this cake...

LOL - I suppose i could have said they came out with an industrial portable crusher and left him a cube in the driveway - while 4 black helicopters hovered overhead.
Looks like it started with a kernal of fact - the motor exists. Most likely a car executive got one off the floor with an industrial motor and never intended to be resold.... or a guy just got a used car that some one had put an industrial 6 in it and when he went to get parts they didnt have any info on the industrial 6's... from there it went like a game of creative telephone. All I added, from what I had been told, was additional head bolts (felt guilty stupid right after I hit post)
