Does anyone know any history on this car

I knew a racer in the 80's with a car like that in Md. He raced at Capital Raceway. He moved away could be the same, his was purple... His first name was Buddy ? I cant remember his last name.

The guy I got it from claimed it was built locally by a well known now deciest Mopar guru. However I went over to his shop a few times during the late 80's & 90's & he was no longer building anything. He had a lot of race cars over there, but I never saw this one. And I have asked other local Mopar folks who race & only one claims to ever remember seeing a purple Cuda in the area. That's why I posted this add. I just want to see some real doc. info on it. And really want to know who built it. Somebody spent a lot of time on it. Would like to know if it was a winner too.
