Actually, the bore is 4.233" and the stroke is 3.78" which comes out to 426. Mopar had just come out with the 426, so Ford called their new V-8 a "427" so as not to confuse it with mopar's 426, as at that time, engine sizes were marketed more, more of a
PR thing. When Ford came out with their "428", with bore and stroke of 4.13" and 3.98", the displacement was actually 427", but they called that engine a 428 to distinguish it from the 427 they came out with several years earlier.
