You gotta love peoples "car knowledge"

This must have been 25 years ago. Had own my Fastback FS 383 for a couple of years, working on it.
There was a gas station with a garage at the place where I was living at the time, and the guy who owned the garage did also have a -67 Fastback FS with a 273 engine.
Got to talk with him and I explained that I too had a -67 FS but with a 383 engine... And he explained to me that Chrysler never did a Fastback with a 383 engine. I told him that I had checked the vin# and they matched a 383 car...but noo, he told that his brother and I quote " He´s brainded on everything but Mopar and he´d said that they didn´t ever made a Fastback with a 383"... I told him I got bad news about his brother....never talked with the guy again.
