Yep, a turbo. I am trying to decide between 1 or 2. My other business venture is with my brother who started out selling STS turbo systems...

The 6.0L has a larger bore than a 5.3L, same crank throw. there are some other differences like cam size etc... Is this what you were looking for?

I did make it up there to check it out and it will be possible to fit 2 under there. I also talked to another bodyman that did some work on the cab, he said that he may have some time to work on it..
