The create engines have routinely dyno'd at 410+ every time. Do keep in mind that they have a 9.0-1 comp ratio and stock Magnum heads minus the springs to work with the cam. It is a really nice platform to go from.
Now think what the head could be with a capable porter and a slight milling. A few guys here were/are running them in Dusters to low 12's with the create engine OOTB and 11's when the car is put on a weight loose program.
