I call bs, chrysler didn't offer the 400 with a 4 bbl carburetor in 1972, he needs to show the fender tag or build sheet, it should say either E68 or E64, otherwise it's just a run of the mill base 2bbl with parts slapped on it
I went and looked at this car a few weeks ago, I came to the same conclusion. I'm looking for a body that's in better shape than my 77 cop car, but the quarters and floors are gone on this one too and filled with bondo.
