A cool thing that happened to me once a long while back: I bought a 69 'Bird about a 100 miles north of me from a gal that lived way out in the woods. $1000 was what it went for. I bought it because it was a solid car. That, and it had a 428 in it. I restored it to look like a 400 car. I mean every detail was changed to what a 400 car would have. There were no 400 car parts on it when I bought it. This was before the PHS craze. At least, I wasn't buying the PHS back in the 80's. The 90's roll around and the big push for originality came along. Just for grins, I sent for the PHS on my cloned 400 car. Guess what? It was originally factory built as a 400 car! This will go to show you how much these cars get changed back and forth over the years.
