1968 340 intake manifold

A '68 Dart GT with a 273? All the ones I've had were 318 cars. I thought just the 170 and 270 came with the 273....interesting. Is it a Canadian version? I've also never seen a 727 behind a 273 from the factory either. What are the fender tag codes for that car?


Could be some "built for export" car. His profile says Switzerland.
