| Ellen, I know nothing about drag racing. But, in NASCAR all the car are considered "stock" meaning that they are supposed to be like the cars you drive off the showroom when an average citizen buys a new car. However, none of the cars are stock because you cannot buy a new car that resembles any of them. NASCAR has about 32 templates that officials lay on the body of the cars. NASCAR wants all the cars to be as close to the same as possible, So, cars have to fit at least 18 of the total templates. If they do not, the car is considered illegal for racing in the NASCAR circuit. NASCAR has 3 race series--Cup, Busch, and the Truck. The main difference in the Cup (like the major leagues) and the Busch (like the minor leagues) is horsepower. The engines in the Busch series have a different carb to reduce air to the engines and thus reducing hp. The truck series have small trucks racing each other. I hope that I answered your question. |
