forget the HP
forget the HP ratings.....torque rating is where it's at, and the 4.0 OHV does have a good torque rating at a very usable rpm! Granted the engine is not high on horsepower, it's torque is very good. That is why these trucks pull well (up hills etc...) You will notice that ford engines usually have lower horespower ratings than competitors, yet the torque is usually better and at a much lower rpm.
