65 Dart race car

This car may have a history that is unknown to me. Before being heavily modified by the previous owner, it looks like it may have been some sort of factory race car. That is a Commando exhaust cut out on the rear valance, on a sedan. Also was a v8 4 speed with front disc and sway bar. There are no signs of extended road use or wear. No rust anywhere, no wiper burn or fog in the windshield, the tail lights are the nicest that I have ever seen.
