If you had 2.73's your rpms will be about 750 rpm higher on the highway.
2600 rpm at 75 vs about 1850.
Your engine will be turning faster per given speed.
Thats the whole idea for faster acceleration.

i have the 323s right now, so it might be even less of a difference.

Yes with 3.23s your increase will be half a turn more instead of a full turn from 2.73 however yoyr rpms at speed will still be 2600 at 75 and 2800 at 80 mph with stock height tires.
