i just put the order in for a 04 with twin 377s (6.2s) the step hull will give it more bow lift and help with drag. Next fall i will be putting blowers on mine. Whipples i hope.

I had mine done a few years ago with zero gain. Bottom line, mine was very good to start with. However, other boats have picked up 4-5 MPH. Thing to keep in mind is how is your bottom now. I had mine done for less than 1K. $2,500 is very high. When they blue-print, they only work on the wetted surface area when the boat is on plane.
