I've had a '71 340 in it since 2012. I had it long blocked in 2020 and last weekend was the first long ride with the new set up "quasi-tuned". Still hunting down bugs but I think it's close! I've had the same 904 in there since I bought the car in Tacoma in 2011. I added a Frank Lupo 9.5 TC at some point. That orange pre-dates me as well.
wicked nice Dart BTW. Mine'll be green in the next life I think!
