    If you buy a 6.0 with transmission, it can be any year since they'll be matched up. The 2002 and newer engine will mate up to the 5.3L transmission without issue.

    you swap the 4.8 accessories to the 6.0 engine, its dimensionally the same. You need the 6.0 injectors and to have the tune updated for the 6.0. Transfer all the sensors, wiring and accessories from the 4.8. You only use the 6.0 long block and injectors.

    If you do the 4.8L 5-speed truck, just buy a '02 and newer 6.0L. Listen to Red on this---its almost all the same, except for a few small things. The NV3500 can be easily converted to a T-56. That would be one helluva bad as truck. DOOOOOOO IIIIT!
