You are left with a few distinct logical choices, because the engine is SAE rated at 460hp.
1. It's not SAE rated at 460hp, in other words, they are lying. Ford is in fact saying it's SAE rated for 460hp. I don't see the same being claimed by BMW, who is notorious for advertising WHP and not crank HP numbers, so this would be a first for Ford. Sometimes the claims of being "underated" are simply due to not understanding some of the conditions of the test or some of the characteristics of the car, in some cases, it is true. Subaru had a marketing line a few years ago for their turbo cars which was, "don't compare HP, compare the 0-60 numbers!", what they didn't add was that the 0-60 numbers were a function of 5000 rpm clutch-drops with AWD, from a roll, the 0-60s were dismal, because they were down so far on the HP. People thought they were "underated" because of the standing 0-60 times. So either the Ford engine is SAE 460, or they are being dishonest.
2. Ford has magically found some cure for drivetrain losses and invented bearings with no drag and shafts that do not flex, etc.
3. The numbers of these dynos vary, just like all dynos do, because they are not standardized. The difference between saying it's SAE vs. seeing the documentation and certification.
