^ This. The 6.0 was a great engine that got kicked out the front door to go to work effectively only half dressed, with a gluten allergy and a lunch pail full of Wonder Bread. Lol.
Finish dressing it (studs) and get rid of the gluten (EGR) and a couple other little things and they're as solid as any of the engines out there.
And nothing sounds as cool as a straight piped 6.0 that is still wearing it's vgt!
Was it a problem. Undeniably yes, and it was/is more work than most care to who should not have to dump money on top of paying a premium price for a vehicle that could lift a head just driving to the store for some gluten free flower.
