I was going to build a Gasser using a Valiant. The rules say 67 darts are allowed. They have now changed that . Only 67 Novas . Mopars are 66 and earlier. Just something to check into before building a car you cannot race in the class. I read the rules and then called "East Coast Gassers" The Dart was listed as OK but not the Valiant. When I called he informed me the Dart was listed but was a mistake. Only 67's allowed were Novas. All other cars need to be 66 and earlier.
