Maybe another one to add to your list of info.
This car is a clone. He has been trying to sell it on Craigslist for a while now. He bought it a few months ago off of Craigslist in Oregon for 6,500. At first his posts said "clone", now he appears to be billing it as the real deal. I don't know about the appraisal, but dart4forte is correct in what he said about the price for a '71 340 transplant.
I saw that same car at the Salem show several years ago. If memory serves me right the floors on that car have issues. I personally don't know this guy but when I first talked with him he gave me the impression that it was a legit car then he started talking "Tribute Car" which to me is another way of saying clone.
i have talked to that guy, he is a real peice of work!!! thinks because he swapped a 340 into his beater its now a 340 car. pretty rude when you call him on it too.
being in western Canada i have seen a bunch of 71 340 darts over the years, i know where are a couple are. seeing this post reminded me to go check on one. not sure f its for sale or not but have to ask will check in the next few weeks.
