Dart Charger badges

My '65 GT was a hand-me-down, have owned for 15 years. My Aunt bought it new in '65, drove it until she was 91, then handed me the keys. It's all original except for the few upgrades I have installed. Disc brakes on the front, new springs on the rear, and Ralley wheels. Pics below, the"273 4BBL" decal is aspirational. I have been looking for an Edelbrock D4B, where did you find yours?

Nothing on that engine says Charger except the pie pan. Are you sure it's a 273 HP?
I had a HP engine that some previous owner had converted into a low compression engine, so it's possible you have a HP engine that someone has replaced all the Charger trim with 2 barrel stuff. The fender tag will tell.
