4.8 to 5.3 swap ?

[Overdriven]

If the engine had dod or vvt, to delete them he'll also need new lifters in addition to the cam. I think there's something else that needs to be swapped in the timing set too, it in the ecu it's just an option that gets disabled.

All the truck intakes are the same so not much point to swap everything. The only difference with intakes is return or returnless fuel rails and drive by wire or cable throttle. In my opinion not much point in going through the hassle of switching from one to the other. Unless he plans on doing something like turbo and wants to prepare for it then by all means do what is necessary.
