10-15 MPH faster then a stock 502 mag! With the right set-up of course...props, drives, and driver! I'd guess 70-75?!?

I have a '95 271sr1 with a 575sci and a 1.5 XR. Probably similar power to your combination. Depending on the load and the ambient temp I swap between a Mercury Racing labbed 26p Bravo or a standard 26p Bravo. One of these days I'll catch a tail wind to blow me over 74. Hope that gives you an idea.

Thanks fellows. I was thinking pretty close to those #'s myself . Prop is 28 p labbed four blade. Extreemly new to high performance boating. So I guess top speed souldn't be a concern for a while 
. The motor is being built as we type.
