Johnny - if you make lots of torque down low in the rpm range, you'll have a nice STREET engine. You won't need to downchange to pass other cars, and you won't need heaps of rpm to accelerate from a standing start. You will not be able to keep up with guys that have the same torque peak at a higher rpm. Provided the other guy built his drivetrain to suit (ie: trans and diff gearing to suit the torque curve), he will out accelerate you all the time.
An example of why higher torque peaks help you accelerate :
A Formula 1 car is reputed to have (around) 320lb/ft torque. Many, many Cobra owners here would have more than that, and their motors certainly didn't cost hundreds of millions of dollars in development and research. The difference is that the F1 motors make their (apparently low) peak torque of 14,000rpm!!!!!  
Cobra motor: 320lb/ft @4,900 = 298hp
F1 motor : 320lb/ft @ 14,000rpm = 853hp
