What gear ratio for a street car w/occasional track use?

I've decided that I think I want to swap out my 3.55 gears in my 68 Dart 408 stroker. It's a 4 speed manual with the 2.44 (I believe that's what it was?) 1st gear. After this last tuning session its making roughly 500 hp and 540 ft/lbs torque. I'm running a 28x12.5-15 Bias ply wrinkle wall tire.

I'm just not as happy with the 3.55's as I thought I would be. Thinking I should have gone 3.73 or 3.91's.

It will spend 95% of its time on the street with spirited stoplight to stoplight driving and some highway to get to shows within a half hour or so. Probably 3-4 times a summer I'll take it to the track. Am I crazy wanting to change the gearing being its not a track car?

Currently it cruises at about 3000 rpm at 70.
