Yes, essentially 1970 was the last year for the 340 in the Dart Swinger but two dealerships up here in Western Canada pulled off a bit of coup when they convinced Chrysler head office to run a batch of sixty five '71's just for them. Then in '72, that order must have stayed in the 'head offices' heads, because they gave 2 dealerships 50+ of these stripped down performance hotrods for blowing out a bunch of inventory, just for them. But, yeah, get the full story here:
