2.76 vs 3.23 vs 3.55

with the tiny little tires you have 3.23's won't be horrible. In fact with those tires I wouldn't even recommend 3.55's if you plan on hitting 80 on the freeway, 3.55's and those tires would mean turning 4,100 rpm to hit 80. Even the 3.23's will put you over 3,700 rpm at 80. Anything much over 3,500 gets old pretty fast.

Off the line acceleration is cool, but if you're driving your car on the street and are planning to take it on 300 mile trips the cruising RPM is much more important. Sure, you could run 4.56's and make it a burn out machine, but you'll then be driving to Havasu at 65 mph listening to the engine scream and watching your gas gauge plummet the whole way.
