1964-65 Barracuda question

My friend just called me to ask about a 1964-65 Barracuda. He said it had a 150mph speedometer and a factory tach. It has a 273 with commando on the air cleaner and dual exhaust. Is this car anything special, or just a routine Barracuda? I know that a few high performance models were produced in these years, but I'm not sure if this could be one of them. I told him to check and see what rear is in it, because I heard that the hipo cars had an 8 3/4. If anyone has more info on this I would appreciate it. Thanks Mike
