Don't do a 4.8, you'll hate that.
Find a GEN 4 5.3 from 2010+ because of the VVT, then plop the whole thing in there. You will have to flash the computer with a tune file that will support the smaller 5.3 engine. A simple copy/paste of information from a 2011 5.3 file would do the trick with HP Tuners.
