Check out "jupiter valero's" a-21 in the "props, setup, and rigging" section. Some good info and he might be able to help out.

There is a lot more speed in it but you need to buy some parts. A jack plate and water pressure gauge would be a good start, raise the motor and you will pick up rpm's and speed until you run out of water pressure. Then it's time for a low water pickup.

Like what ydo said jupiter has some info on his that will help out.

Great looking hull though

After reviewing your pictures above you first need to add a hyd. jackplate and increase your setback to about 12". You'll need low water pickups and a nose cone. Make sure you have a good water pressure gage and temperature gage. Your new setup should yield speeds well into the mid to upper 80's..maybe even 90+.
