It is all the same torque and rpm are equal to horsepower. The problem is when people think they do two different things. But torque alone doesn't give a full picture of an engines capability that's why the concept of hp was invented. Cause for eg. if engine A makes 500 lbs-ft and engine B makes 350 lbs-ft that really don't tell us anything. But if you said engine A makes 200 hp and B makes 700 hp then the picture becomes clearer.
Another eg. take two engine with identical powerbands but are 1000 rpms apart so let say one goes from 1000-6000 and the other goes from 2000-7000 obviously we the first one has more torque but really that don't mean anything if both are geared proper (proper in this case is fastest et). The second car would be just as fast cause he's hit the same hp along with the first car at the same time.
