Transmission may not last too long depending on how you drive it, what 6.0 it is, and what you are planning on doing to it.

Perferably an LQ9. I've heard the transmisson may go if you have higher HP. I'd only be doing headers back exhaust, intake, and tune.

6.0 complete engine including all belt driven accessories computer and harness

new engine mounts and registers

complete exhaust setup

not sure about the tranny, i know that the 4l60e will mate up, so im assuming that your tranny will to but for durability i would do a rebuild or swap.

tune really wouldnt be required unless you keep your 4.3 pcm

new intake setup may be needed or wanted.

its not as bad as its said to be just a huge amount of work if you cant find a 6.0 ready to drop in complete
