Do you want to explain to the class how to figure out how much Horsepower an engine makes? Because it seems that you believe and preach that engine torque is not that important. Explain in full detail how making making horsepower is more important than making torque even though you cannot have one measurement without the other.
HP is what's ultimately important it doesn't matter what ratio of torque and rpm you make if from especially from a performance perspective eg.. I need X hp to do Y. The ratio of torque and rpm for a given hp is more of a design issue.
