Can someone tell me anything about this Duster?

Its a red '72 340/4sp w/black stripes- they are not factory stripes now, but I have no idea when this style was painted on. Was told it was raced in some southern state (GA?) for a number of years before it was sold to someone in New Jersey. I purchased it from our member 66Cuda in MI. who had it stored for the past 5+ years. Hoped that someone may be able to identify the car so that I can get an idea of some of its past.

Thanks,
