and Yes, nascar engines and sprint car engines are two different beasts. Sprint cars are on a short oval tracka and they need torque to accelerate off the corners. Nascar engines run in a vey narrow band...I think I read it was 300rpm. Because they are running full out most of the time on giant ovals, acceleration out of the corners is not that important since their speed is much more constant.
