gear ratios and torque

I'm cross posting this from another forum, Hello, question...how much rear wheel torque is lost from a 3:23 gear vs a 3:55 gear? everybody seems to concentrate on hp and 1/4 mile, but my car will be for old school light to light fun so in my way of thinking I'm using torque as my yard stick. I already have perfectly good 3:23's
Thanks
