Is this really true

[Scott H in Wheaton]

Maybe that's the engine Ford has been looking for in the last 70 years...you know the story, its a factory experimental and was never supposed to be sold, it has a carburetor that gets 100mpg and the oil industry and automakers don't want the public to know because it would kill profits, etc etc

Making a one-off engine with a 4" crank and spending the time to at the factory to port the engine just doesn't jive with assembly line production methods used in the 40's.

Is he claiming it was something done for the war effort?
Mac Van Pelt might know something if anything is available on it.
