The first pic of the car with the "Batcar" painted on it was taken at Kil Kare Dragway in Xenia, OH.

If you look at the tower you can make out the name.
The last pic of the car racing was taken at National Trails Raceway in Kirkersville, OH. Both tracks are still there and racing.
Maxton Chevrolet is still in existance, and is still selling hi-performance Chevys. They sold 5 COPO Camaros in '69, all of them still inexistance, one owned by a member here.
I have posted pics of Maxtons Friday night cruis-ins many times in the lounge.
Great find, Chris. This car has found a great new home.
