Gear ratio question

[RDuke]

Hi guys,

Quick question for those of you who have/drive high HP cars on the street. I'm going back and forth between 3:25 and 3:50 rear gear ratio's on my current project I'm building. I'm playing with ratio calculators online and I'm leaning towards 3:25, but wanted to know any other options.

Combo:
Wanger built LS supercharged (1K hp, 850tq, with lots of low down torque).
4L80e trans (final 4th gear ratio I believe is .75)
28" tall tire (27.9 actually, 335/30/R20's)
Street car only, mostly around town with some highway/longer trips.

Am I right to think that the 3:25 is better since it has such high torque at a lower RPM? My thoughts, similar to a turbo car, it would use more of the torque/boost through the RPM range.

I recall Charley on his Rivi swapped out low 3 something gears for high 2 something after about 5K miles and he's about the same HP/Trans combo. is 3:25 too high, just right?
