Guess the HP

610 TQ at 4,400 rpm
570 HP at 5,600 rpm

I think your HP curve peak will be limited by that small carb. But it will also make the car much more drivable at lower rpm, if this is for a street car.
Well it's for race only. I hope you're not right lol.
The blp 850 is supposed to flow over 1000cfm but that was with downleg boosters
