Dodge: Dart VERY RARE FIND!
No they came out in a Dart in 1968.
I don't think so since I own a 1969 Dart 340
I believe this is the only A body with one year only 340 option. Also last year of 340I had a 73 340 Dart Sport.
He clearly states that he is talking about the 70-72 Dart body style!! Of course, he also mentions something about a "Magical Moment", so add those two together and you need a wheel barrow to haul around his description!!
