64 Barracuda pace car?

Wow! 4th of July 1964. I didn’t think the Formula S came out until 1965. The exhaust tip says it all, in my opinion. I hope someone can come up with some info on this car. Two other things from the film - Look at AJ’s race face. Classic Foyt. Also, beauty queens in bathing suits. Could you even do that today? I miss the good old days. Real cars, real hard core drivers, and tuners; Smokey Yunick, Curtis Turner… I haven’t watched stock car racing in years. But man, a Barracuda pace car! I was looking for a Formula S Barracuda when I found my Dart GoGo. I’d never heard of Dart Chargers, or GoGo’s, but I recognized the engine.
