You can swap it, you need to do some modifications.
The Gen IV has a 58X reluctor wheel crank, camshaft reluctor on the front( and also different count), knock sensors on different locations and I can't recall what else at the moment.
There's a Lingenfelter conversion box that addresses the crank/cam count differences. Look up "Gen IV swap in Gen III" or something like that on the Internet. Lots of good information out there.
Or, just find yourself a Gen III 6.0. That'll be a direct swap for your 4.8. Literally plug and play. Just get a computer reflash and off you go. 🛻

Where in TX are you located? I may be getting my hands on a Gen 3 6.0 here soon.

That is a fair point. Just close your eyes when you look at the bearings.
