Pretty crazy, but why chop up a real 55 when he could have just used the repoduction body. I mean it's not like the "real" body adds anything to the car anymore. They totally gutted it.
As a side note, I have a 1955 Chevy truck that is in the middle of a frame off rebuild. I had a all aluminum jaguar v12 that I was going to put in it just to be different. The engine looked bad aruse but seemed like they were a lot of problems so I ended up selling it.
The engine looked like this one..
