The easiest route here is to put whatever V8 you want into the 4x4 truck, take the V8 engine harness and computer and swap it into the other truck. Wiring harness for both 5.0 and 5.8 are the same with some minor exceptions that won't affect engine operation(5.8 has no knock sensor). You will also need the V8 frame towers and engine mounts and the rad, and a matching flywheel/flexplate for whatever tranny the truck has, you can't use the I6 flexplate on either motor.
