My 97z had 2.73s in it and I went to 3.73s and Yank SS3600 and it was a big improvement. I have about 80 1/4 mi. passes on in the last 2 years & my 10 bolt is still holding up. I would get GM or Motive performance gears, I have Richmonds and they have a fair amount of wine to them.
Gear ratio should depend on how you are going to use the car. If you want the best out of your 1/4 ET's then you want a ratio that will accommodate your powerband in the most efficient way (being as close to your power peak as possible in the traps).
If you are just going to tool around town then get whatever ratio you can tolerate.

Did you just say "Tool Around Town"? HA!!! That's awesome!
If you're gonna have alot of power runnin through there go ahead with a 9".
There's no use in risking killing a 10 bolt with what you're planning.
