1965 Dodge Dart Charger

That engine was from a 1965 Barracuda Formula S built in December 1964. The interesting is that it had one owner since day one. He got rear ended and the car was parked. I bought the engine before they cruched the car. Now when I looked up the engine I was confused that this tag was there. The block is cast in February and the car was built in December!

What I know of Chrysler didn't built any Charger/Commande engines before late July! Can it be a pre-production built engine?

No clue at all on this one! But I have never seen that tag on a 273. That's for sure.
