everything between the 4.8 and 6.0 will bolt up. I don`t know what will have to be changed to make the 80e fit, probably the driveshaft length and trans mount.
To make the 80e work you will have to change the positions of a couple wires and add a couple wires. You will also have to have the PCM re-tuned to control the 80e and 6.0l
