After the engine in our '09 V10 6.8L F250 'sploded 3 days ago, we ended up with a new-to-us replacement '12 GMC 2500HD that we were able to find on very short notice. The V10 6.8L was rated 362HP w...

Unless you have an infinitely variable transmission an engine needs to deliver power to the transmission over a range of rpm. The power the engine is capable of making over that rpm range is described by the HP and torque specifications. Torque at rpm is power. If two engines make identical peak horsepower at 4800 rpm but have different peak torque numbers, the engine with the higher torque is the more powerful engine and will pull better.
Nope, identical power. Yes, there can be minor differences depending on the torque curve and gearing, but all this is hypothetical.
Higher torque will get you off the line faster and up to speed faster with the higher rotational force to the wheels. A vehicle with higher torque will have a easier time getting its load moving.
