What props are the best for a no step, 650hp, standoff boxes and bravo XR drive on a 2000 Top Gun

Last year I was running 625hp and Labbed 28 bravo 1 s' at 5400rpm at 78-79 mph on gps But I did not have stand off box's
Don

28's non labbed. 81 GPS with same HP turning in. A mile or so less if out I would expect. No boxes.

I am running labbed 29s on XRs (no boxes) at 5200 with 550hp at 78.4mph with half tanks on 99 straight bottom, I tried 30s yesterday and couldnt get the RPMs, I know where you can get a set of 30s, they should work great with 650hp

Wild

At what RPM

I have a set of 4 blade 30s for sale.
off my buddies 95 gun.
he was running 640 hp with xrs no boxes 83mph half tank of fuel

Wild; Who labbed your 29's And are they Bravo 4 blades? On the 30's what RPM's were you able to turn?
