I have been throwing around the idea here lately about putting a 6.0 in my 2000 Sierra
4x4. Currently it has a 5.3 with a 4L60e. How hard would it be to do that swap? Would I be better swapping the 4L60 for a 4L80? I want it to have some power just not ungodly, maybe keep it about 400hp. I know im not going to get any fuel milage as it is since there is 10 inches of lift under it anyways. I just want a reliable truck that can work around the farm and tow a few things here and there. Let me know your ideas please and point me in the right direction.
