It can be done, but it ain't easy, aside from the v8 motor, you'll at least need the computer, main harness from the donor truck. You'll need to use the bell housing from the v6 for the tranny though, the bell housing on the v8 has a different bolt pattern.
If you aren't pulling that far, it might make more sense to put in 3.73 or 4.10 gears and some type of LS diff and an aftermarket tranny cooler, prolly cheaper and easier.
Whaddya mean I dont pay my bills?? Whydya think I'm broke!!
