I used the calculator on Moparts, which a lot of us have used forever, and it says 412.5 at the tire, not flywheel.
Have taken known times at the track and dyno and compared them and this calculator seems to be mighty close.
Example, my old car made 708 when Best Machine dynoed it. Ran 140@3200 pounds. Plug it into this same calculator and everything matches..... lol... who knows
