My opinion, he's got an interesting custom T'bird, nothing more. I think he's reading into what he's seeing on his car. There's nothing to suggest that it's anything more than a custom with some performance mods too. Most guys who are into customs, are at least somewhat into performance too and it's not uncommon at all to modify for performance and looks. Sometimes, a guy goes to build a racer, gets bored with it and ends up turning it into a show car (or the other way around).
I doubt that we'll ever know the real story behind it, but any suggestion that this is some kind of Ford prototype is a long shot at best.
