    They are different, I ran one of those set ups several years behind a above avg 3406B. 3.70's and tall 24's. Tapered bearings on the counter shafts, a lube pump and a cooler go a long way. Even empty on a grade or big head wind you will hear the pitch of the whine change, when it does drop it back to direct. Once I learned that I had pretty good luck with it.
