I just got my 6.0L engine to swap into my 04' that had a 5.3 engine. The engine I got has the 3 bolt throttle body, and has 9k miles on it. If I want to keep the 6.0L intake and throttle body, what do i need to do. I have been lookingat post and haven't found a good answer. everything looks the same right down to the fuel rails.
