I wouldn't buy any props unless the engine was dyno'ed at a reputable shop. 575HP @ 5300 from a 454 is probably an unlikely number, unless they have blowers on them.
Id bolt the stock 25 3 blades on and go for a run. How much RPM you gain with those props, will give a good idea of how much power you picked up. One speed run shouldn't hurt anything if they still have the 440HP bottom ends or better, and a decent cam/springs. Then once you get those numbers, I'd call Bret at Bblades.

Could you post some good pics of your race fairing. Profile and some dimensions.
Would be greatly appreciated. Hope your project is advancing as you wanted.
