Re: Finding the Year on a Ford 400
Hi, I can't help you with the year/s of the 400 cu in engine, but what I do remember is that the 400 was considered a smog engine. Instead of calling it a Cleveland, it was called an "M" engine. Ford called it an "M" engine meaning "Modified". Other rumors were that it was called an "M" engine because of where in Canada it was built. In stock form it was not very powerful for it's size, and again, it was because it was made to reduce emissions. Also, if memory serves me correct, the easiest way to tell a 400 M from a 351 Cleveland was the thermostat location.
