Love the color and the soft drink! IIRC, MOPAR made a series of street legal HEMI Darts labeled "Baby Grands".
You're thinking of the 1966 D/Stock Dart. It had a 273 with bigger carb,hotter cam, and a set of headers in them. They never made a Hemi Dart for the street. All LO23 Darts where sold as is and with no titles IIRC. Now you could get a 340 and 383 in the GTS in 68. Then in 69 you could get a 340 in the Swinger and 340, 383, and 440 in the GTS. But no Hemi's.
But back to this model. I love the color! And the wheel choice!
