Torque gets you going, HP tells you how fast you can go.
Torque can be multiplied. HP can't.
At see level, if Ford made a 440 hp version of the 7.3L, it would pull hills at exactly the same speed as the current 6.7L. Because the 6.7L makes more torque, it will accelerate a heavy load quicker than the 7.3L, unless Ford puts in much lower rear gears, to make the Tractive Force (engine torque * transmission reduction ratio * differential reduction div by tire radius) equivalent.
This new engine has some design features to allow for future power increases. My suspicion is that whenever the 6.7L gets a hp bump, this motor will too. They'll reserve the top HP rating for their premium (i.e. high margin) 6.7L, while keeping the 7.3L numbers competitive with other gas motors.
