Nostalgia Pro Street is designed for heavyweight vehicles that emulate the original Pro Street movement of the ’90s. The engines are conventional-style bullets with a single stage of nitrous, and the cars weigh in the 3,200-pound range. Defending series champion Jeff Colletta unveiled his new ’69 Camaro RS/SS this year. It runs a 640ci engine that uses a Dart block and cylinder heads, and it goes 7.30s. The car is as much a show vehicle as it is a race car.
