Default Rear End Differentials

I have a 1990 L98 coupe with a Thermo Master Hypertech Chip and a 160 PowerStat, Cat Back Exhaust. I'm not happy with my 1/4 mi. et.
The rear-end is stock, what kind of rear-end would be good for track and street and what could I expect from it?

Thanks
Jim

auto or std trans? If auto, I have found the 3.33D44 works well. If std, then you already have the 3.33D44 or the option 3.54D44, which are both good rear gears.
