I still have that Mopar action floating around with the(your car) black A12,the tech guy Ehburger or whatever his name was, used it as a reference resto,it was a beautiful car. A12's were rare even back in the day I remember a guy whose wife used to work with my mom owned Big John's,that was a long long time ago.Most of the runners I remember had either 383's or Hemi's.The one you have now John is beautiful.
