If NHRA or IHRA wanted to, they could take one to a chassis dyno and see what they make at the tires. The LT1 and LS1 cars made more at the rear tires than the factory flywheel ratings. Should be off about 15% with a stick car. My everyday driver is an untouched '98 WS6 (ram air) LS1 automatic Trans Am convert. It makes 326 at the tires. A decent stick version makes closer to 340. What are they finally factored at now?? Even if they started off with the rwhp numbers, it would surely be closer than what Ford (or any mfgr) rates them.

Won't make everybody happy, but would be closer than advertised hp for sure. Could save a year or more with the AHFS handling it. Might cost somebody an hour's worth of time. You would want an untouched vehicle, not one that could have been de-tuned by the mfgr or racer before be presented for testing. NASCAR uses a Dynojet just like mine for spot testing cup cars after races to keep the different brands competitive with each other. Simplest thing it the world to do. The numbers can't be skewed by the operator as with many other brands.
