Cuda on the bay misrepresented

Well, I'm not a Barracuda expert but the guy doesn't know squat about vin decoding. Also I have never heard of a 275 horse 273 except in a 66 D Dart. Correct me if I'm wrong. I could only find the Formula S designation on the broadcast sheet charts and not in the vin. Also aren't those AMC style Magnum 500's
on the front? I didn't think they were made for small bolt pattern. toolman
