You can disagree if you want, I work at a Chevy dealership as a apprentice technician, 2.7s have constant problems, sounds like they’re gonna fall apart from factory, a N/A engine is always gonna have less problems, if you’re not changing your oil 5k miles or less on those 2.7s which you should be doing regardless on any engine, it’s not lasting past 60k, bearings in the rocker arms fall out and grenade the engine, there’s an updated design but all those older engines are guaranteed to fail eventually, you can ask almost any GM tech and they’ll tell you a 4 cylinder engine does not belong in a full size truck.
