1973 Dodge Dart Sport

Wow...learned something new.. I've been feeling good about a. 72 Demon ''survior' I just bought.. All original sheet metal, original paint car.. Only thing not original is the engine.. I guess I'll stop thinking of it as a survivor.... I had no idea there was an actual criteria. Thanks for the info..!
There are exceptions on some engines.
If the engine was replaced under warranty for instance. But it would have to be the same size. No replacing a /6 with a 440. Depending on the classification, you would have to produce documentation that the engine was replaced under warranty.
It's getting tougher to get these cars to shows. So the bar get lowered and lowered.
