Dynoed:
175hp@3,400rpm & 388tq@1,800rpm.
Based on those numbers I'd say build your truck around taking advantage of the torque and ignoring the horsepower.
Torque is what moves you.
I do think I'd be a little disappointed by less than 200 horse from a motor that big, but 3,400 is on the slow side for big horsepower numbers and I don't think you want to turn this motor fast enough to change that.
