That's a lot of good info, as far as fitment goes would the 5.3 and trans fit just the same as a 6.0 with the 4l80? And what kind of chassis reinforcement am I looking at? I think I've read the steering box needs moved, what about cutting a tunnel and motor mounts? Also I don't think I mentioned, but I would prefer it to be auto so the rest of the family can drive it too.
