I also raced in the old NSS class years ago with a 68 Dart,great bunch of racers I must say.I remember when the 1965 cars were thrown out of the M/W class.Thats one of the reasons J.J. started the NSS class. I also believe if they would just open up the carb rule to allow single 4 "Carter,Edelbrock" carb the car count would go up. As far as the purist thing goes,then everyone would have to run a crossram intake. Just my opinion flame on.
