I sold a kid a 400 Chevy, he put it in a '66 Slick, and you know what? It dropped in to the factory mounts like it grew there! The back X-member needed some fabbing, but he was on the road in one weekend. Did Henry have some spies somewhere, or maybe an evil plan? Or did he foresee the present crisis and was just getting ready for a takeover of GM? Haha.
