Three-on-the-Tree with 273 4/bbl?

My first car was a 65 Dart 270 with a Hp 273 and a 3 speed column shift. Now I found out it was one of very few built with that combination. I think Ulf has the numbers. @65dartcharger
Well there you have it! I knew Mike would know. I'd like to see one of those. I bet is was cool.
