How hard would it be to swap out a 6.0 with a 7.3? I have a 04' with a 6.0 that may have a blown head, needs a new turbo, and might need a new egr sensor. I also have a 03' with a 7.3 that I rolled a few months back but still runs fine. Is there many complications to swap them out? I have both trucks and both trucks run with all the parts. ANy thoughts?

Thanks
Michael
