Is this odd or?

Being that it has front discs also, I'm inclined to believe it is a factory V8 car. You should try and dig around for the build sheet, see if you come up with anything to support either. VIN and title mishaps did and do happen, though not really often; my daily driver is a 4-dr sedan thats been titled as a wagon since brand new :dontknow:

It's not a Lynch Road car is it? One of my Coronets was and it was all kinds of wonky
