Not sure if you guys read the Mecum ad lately, but it appears all of the references to it being a test car, or an engineering prototype, are now gone. Maybe the Mecum legal team made a few phone calls and realized this guy was a con man. He still says it's a Ram Air 455 H.O. though, when in fact it's a 1968 400.
He also removed the pic of his invoice from his E-Bay ad, and now he says that PHS does not exist for this car. Maybe too many people were laughing at him when they saw his invoice says it's a standard brown 350 2-bbl car.
