I haven’t heard if they will upgrade the tranny on the 6.2, but I’d still go 7.3. If I had to guess, they won’t change the tranny on the 6.2. In my experience, the larger displacement engine always gets really close to the same mpg empty and better under any load. It is the latest technology with the 10 speed tranny, so that’s a bonus as well. There have been many tests on Fast Lane Trucks if you are interested in knowing more about 10 speeds on the lighter trucks.
I’d look seriously at this 7.3 engine if I was shopping for a truck. My only concern is elevation, and it or the 6.2 doesn’t have a turbo. The valley floor in my area is 3000 ft, and it just goes up from there.
