I've seen too much variation from different dynos to guess what it'll make on an unknown one. On Dwayne's I'd think about 630 at 6800 and 555 torque at 5400. The QFT 950 is probably worth 10 HP over the 750 you have.

Whatever it's going into better have at least a 5K stall converter and enough gear to keep the RPM up above 6K most of the time.
