I have a 93 CC 5.2 auto and went from 3.55 to
3.91 and it felt like 50 HP. I was a little
hesitant as are you about the 4.10's. I have
4.10's in my 68 SS396 Chevelle and I did not want
my truck RPM to be that high on highway, but I
figure we do have OD. I am sure the 4.10's would
be fine, but I am VERY happy with my 3.91's.
