I'm pretty sure this one had a history road racing after drag racing. AS= A Sedan, in SCCA Club Racing (non-pro). Unfortunately there is some BS about the documentation on this car. For example here:
1966 Dodge D-Dart Lightweight Trans Am Racer
There's plenty of photos and complete race entry and results for Trans-Am. Too early for me to go digging and I can't remember if people found that a car so marked was or was not entered in T/A races.
