Thanks John. I'm not trying to reinvent the wheel...I'm just trying to help them move a little faster. I should clarify what I meant by "decent pace." I'd honestly be quite happy if I could keep my napco on the road at 55-60 without straining. I have no interest in pushing it to 65 or 70...That'd be crazy without changing to 4.11's or higher. And I just don't have any interest in ripping the OE gears out right now... I suppose it's worth investigation. I know there's a 4.11 kit available now...Tall dollars, and I need two. Granted...I'm not planning on working the truck. It did enough of that in it's former life, and quite honestly, the 4wd parts are far to hard to replace to chance breaking something. So, it may not be sacrilege to ride around for a bit with 4.11's in there.
So, basically, what I should take away from this discussion is this.

If my goal is:

A) improved highway speeds, then really higher gearing is what I need. Couple a 261 with 4.11's and it'll be that much better.

B) more low-end power, then a 261 is for me, but
any improvement in hwy speeds should be taken purely as a happy accident because any improvement in gear ratio that my taller tires will give me.


Thoughts?
