Over the course of the 2000 season, the National Mustang Racers Association's Pure Street class has really come into its own. Certainly Tom Payn has emerged as its first star, but with 20 racers vying for 16 qualifying spots at the Byron, Illinois, race it's easy to see there are plenty of speed freaks interested in naturally aspirated racing.
Of those 20 cars, the top 10 qualified in the 11s. When you consider intake, cam, and head limits on this class (check out the complete rules at www.nmraracing.com/ rules/pure.html), this is simply amazing. "When I read the rules, I thought they did an excellent job," Rick Anderson of Anderson Ford Motorsport says. "It's flat-top pistons, and it's not aggressively milled heads, 58cc combustion chambers. That's something a real guy can put together in his garage. Then it's the long-runner intakes. That's a lot of cars that we've done in the past.
It's still a car that a kid can drive on the street if he wishes and go to the track. That's why we got excited about it, and we wanted to see how far we can push that envelope."
By pushing the envelope, Rick is talking about the new line of cams he is developing for the class. As with his popular cams for the power-adder Renegade classes, these new Pure Street cams are designed to deliver max performance within the rules. When he asked us if we'd like a glimpse at the development process, we jumped at the chance. What our sneak peek tells us is the Pure Street cars are going to run even harder next season.
Pure Street was designed for street-oriented 11- and 12-second small-block, naturally aspirated Fox-chassis Fords, including '96-present 4.6 Mustangs. Limits include a maximum displacement of 310 ci and a maximum tire size of 26.5x10.5 inches as measured. Its 16-car qualified fields run on a pro tree (0.400) NHRA sportsmen ladder.
