www.SuperCarRaces.com is a racing class that features 1955 to 1979 Musclecars. SuperCar has to be 100% Factory stock in appearance on the exterior and interior. No headers after market heads, intakes carbs etc. Under the valve covers in the oil pan you can do anything you want. You can stroke it, you can port the stock heads, raise compression. You must put all the power to the track on threaded polyglas tires. We run our class up and down the east coast from Cecil County to NED. Visit the website for more info.
