SAE requires the engine to be within (I think) 3% of the 'stated rating' on a properly and confirmed correct engine dyno. They cannot have wildly fluctuating power levels in these cars due to need for consistent baselines for repairs and such..
Small fluctuations are normal.. 455 HP, 453 HP, 458 HP, 456 HP...but not 455 HP, 485HP, 425HP, 475HP...
