Beer is riding on an argument.
That's the first/only '72 340 Demon I've seen with Dart emblems on the deck lid, and my 340 Demon sure didn't have that. Is it a Canada thing?
Just found this on-line..

"....There were minimal changes for the ’72 season—including a new grille following the rest of the Dart line, a revised instrument panel, a flat-folding front passenger seat, and a single hood scoop for the 340 in lieu of the outboard twins seen on the ’71s. Base price rose slightly to $2,759. It was also quietly renamed the Dart Demon, with a Dart nameplate appearing on the body. The 340 was “retuned” for 1972, which included a drop in compression; this was also the point where a change in power ratings went into effect. It all added up to the ’72 Demon 340 being rated at 240 horsepower. The 3.91:1 rear end ratio option was also retired.
For 1972, overall Demon sales halved, to 40,000 sold, although once again just over 10,000 Demon 340s were built for the year; as an overall percentage of Demons sold, the Demon 340 doubled its importance in Dodge showrooms. That’s a strong showing for the hot version, particularly as the whole muscle car movement was largely closing up shop. But compared to Plymouth’s 53,000 Duster 340s sold with just a six-month head start, Demon 340’s 20,000 units make it a far rarer beast today, despite the differences being purely cosmetic. Today, it means that on average, a Demon 340 is nearly ten percent more dear than a comparable Duster, with the Demon’s average sale topping $50,000 for a ’71 and $40,000 for a ’72...."
