So last night i broke a rod so the 6.0 has been floating around in my head for awhile now and i have still yet to find all the details on a 6.0 swap to make me fell safe to tackles this project so i have some questions about it. what is everything i would have to do to put a 6.0 in with little to no modification.

What do you have now? What year and engine combo?

I have a 2003 tahoe z-71 package with the 5.3 323 z engine.

Then the 6.0 should be a drop-in. I have a 2013 Tahoe, and the same year Suburban can have either the 5.3 or the 6.0 engine. But the Tahoe only gets the smaller engine.
I believe the bigger engine would get better mileage under identical driving. My old Corvette gets in the mid-20s because the engine only loafs unless its under WFO. So I think the same thing would apply to a big engine Tahoe.
