I would guess if you were running 22's with 454/330hp the gear ratio is 1.5. A good place to start would be 34 or 36's. Did you upgrade the drives ? I would think that your going to have trouble keeping B1's or XR's alive with 750hp.

Thanks for the replies guys, i forgot to check back for updates! ok i found my dyno sheet and attached a pic... i guess im a little bit of a story teller 725HP not 750!! 
i didnt run it what i consider very hard... but it did hit the limiter at 6250 when i leaned on it. i dont have a speedo so i dont know how fast i was going? they are std brovo 1's with 1.5 ratio. i did notice that the little gearbox? that turns the fresh water pump and activates the fuel pumps was puking oil out when run at that RPM?

Prop at 5800.
Let me know if you want some test propellers.

Don't know.
The boat needs to tell you.
You need to go up in pitch to find a sweeter spot or, call me with a exact wet weight and I'll tell you the exact pitch you need to run 5600. But, I need the 6250 R speed as well in GPS form.
