3.55 to 3.92 is only 2-300 rpms difference. These trucks should have had 4.10's standard imo.
Based on your argument, 3.92 - 4.10 is not even a 5% change
and the rpm difference would be 80 rpm @ 2000 rpm
I do agree tho, if you are going 3.92, may as well move up to the 4.10, but to say they should have been stock, not agreeing there
