Gator,
As RJ says, high torque is good for acceleration and high HP is good for high top speed. Good rules of thumb.
Some folks mistakenly come to the conclusion that one can get the high torque (high accel) via gearbox mounted on a small HP motor.
The fallacy in this is that as soon as the motion begins (motion means time) , the torque drops quickly because the small motor does not have the HP (meaning torque per unit time) to keep the torque up at the desired level as the speed increases. Acceleration quickly falls off in this scenario.
From a practical standpoint, the street motorcycles I have tuned have focused on midrange and upper midrange torque rather than high top end HP.
I think the same could be done for street cars too.
Good midrange torque (and the associated HP that occurs at those RPMs) makes for a quicker and more pleasant ride because acceleration is easily available at an instant without having to shift gears and reach for top end HP.
And I always liked the beer glasses in the UK that had the legal fill line near the rim.
I want my $.12 of beer and not a cent less.
