3.23 is the compromise gear. it does well on the fwy, and it's still got some balls around town (especially when paired up with low trans gears).
but for your application? 3.55 would be my choice or heck, even 3.91's would be fine.
that cam starts singing around 3K and with the type of driving you're doing you'll never even get into the chorus with the freeway friendly sets and those tall tires.
big deal if you twist her tail a little bit. it's not like you're hanging it at 4K for hours on the freeway in the slow lane trying to keep up with traffic.
