The Mythical 7 Cylinder V8

That's the questions I asked in the past. In order for this myth to be slightly possible, the engine would have to be built addressing those issues, but l don't have enough information on that. For all I know it could have been a car that was never sold and caught by the dealer and sent back, or it just never happened. Every person that knows this myth has a different story, but how did this myth start? It's very strange in my opinion.
