In order to run the 4L80E you would need a controller for the trans. The factory TCM will not work. In addition, you would need some adapters to make the trans work with a 350. Both things you need to make it work would not be used when you put the 6.0 in. My opinion would be to just wait. It’s not worth the extra money to put the trans in first.
