there are a fair amount of hilly roads out here in so cal wine country, and right now, in the car's present state of tune, can climb the freeway grades at 65mph without unlocking the TC or downshifting into 3rd, so I know from a power perspective, the present gearing is plenty good.
I'm going to play with that fatboy gear calculator and see what my options are. who knows, with the 3.08's and a taller tire, i might have 3rd gear match what 4th gear was before, and have a REALLY tall 4th for flat road economy.
time to play
oh, and as far as the measure of difficulty, it will involve a complete drum to drum rear axle swap, which is not a lot of bolts, but i think my back and my girlfriend are going to hate me...
