I've been browsing the archives and it appears
that most folks obtain higher highway speeds by
replacing the rear end - replacing the standard
3.90 gears. This is what I've been planning to
do also, but before I do I was also wanting to
consider keeping the 3.90 gears and adding
overdrive. My transmission was replaced with an
automatic (350) by a previous owner.
To say I'm an amateur mechanic is probably an
overstatement. This truck is an education for
me - (one which I'm thoroughly enjoying). I was
hoping someone could give me some of the pros and
cons of a new rear end vs. overdrive to help me
with this decision.
This truck will become my daily driver. The highway
speed limit here is 70 mph. I just want to be able
to cruise comfortably at 80 so I can go with the flow.
Thanks for your help,
