It's a real RT 383 auto car --the guy put a 1970 440 in it with a 4 speed. I'm debating whether to go back to a date code 383 auto for a more correct car. The car is in good shape--nice paint. I have a few things to do: bought seat covers from legendary front and back-black because the seats are ripped but not in bad condition. also, the rear end is 323 open. He must have replaced it. I'll look for a sure grip 323 or 355 -if anyone has one for sale................Welcome from Michigan and great looking 71 R/T! Tell us more about it.
