I am trying to decide if I want to change my 3.92's to 3.55's or 3.21's.
Anybody out there have 3.21's in a V8? What do you think of them? Are they
too high? I mostly do interstate/highway driving. I figure 3.55's would drop
me about 250 rpm @ 75 mph while 3.21's would drop me about 475 rpm. I'm
doing about 2600 rpm @ 75 mph right now with approximately 28" (255/55/17)
tires.
