The Ford Mustang Shelby GT500 is coming, and we know exactly when: January 14, 2019. That’s when it’s going to be unveiled at the North American International Auto Show and all of its well-kept secrets will spill out into the ether, and we’ll know exactly how much horsepower comes from its yet-to-be-confirmed multiple-cylinder engine. Okay, we’re at least pretty sure it’s going to have a supercharged V8 -- at least that’s what the teaser Ford revealed last week hints.

Now the prying eyes at the Mustang 6G Forum might have gotten their hands on some insider intel. According to the spec sheet above, the next Shelby GT500 will have 720 hp from a 5.2-liter V8. That puts the next super Shelby ahead of both the Dodge Challenger Hellcat and Chevrolet Camaro ZL1 in horsepower bragging rights. the Dodge Challenger SRT Demon still bests it, but that’s off the assembly line. However, the Challenger Hellcat Redeye -- a Demon deriviative -- will still top the modern muscle horsepower charts at 797.

Now, we have some doubts about the authenticity of this spec sheet. It has consistent and obvious spelling mistakes, and it doesn’t even honor its own guidelines. For example, if you look at the power section, where the 720 hp figure is listed, the box requests the figure in kilowatts. The misspellings could be looked over, but they're doubtful considering Ford (or the vendor here) likely uses the same form across its entire product line, and errors like “Trailor Tow” wouldn’t slip under the radar for too long.

The part that seems to hold the most water is the engine displacement. Considering the new Mustang Cobra Jet and the Mustang Shelby GT350 both sport 5.2-liter V8s, you can almost bet the GT500 will follow suit. With that in mind, the horsepower number doesn’t seem that far off either.

Of course, we’re only speculating until we see the sheet ripped away this January. Until then, we’ll be looking for any tips and leaks to get that information a little early.
