Go with the 3.73's. You will loose a little top end - but since you dont drive up there anyway (NOBODY does) its not a huge deal. You will loose a couple hundred RPM at freeway speeds, but will gain a noticble boost in pull from the bottom end.
get the 3.73's or even 4.10's are ok for daily driver. with my 4.10's when cruising, its not that noticable, but when you get on it the accelleration is much better. the pro's devinately out way the cons. you may lose 1 or 2 mpg's but who cares.
Consider getting a new differential also. They are about 400-450$ and a great mod for future building. There won't be any extra labor since they have toremove the diff from the car anyway. Less $$ when you have to rebuild it later IF you have plans to make more power or going to the track. I'm in the process of buying parts for a new rear end build and will be replacing the diff at the same time.
The 3.73's will be great.
