replacing rear differential grears

I am going to have the gears replaced in my 95 z28. It currently has the 2.73 gears. I think thats right. WOuld it be better to move to 3.73's or keep what it came with. My car does have a few mods but I don't want horrible gas mileage either. Just looking for some opinions.

With the way gas is going up, I'm not sure I would do a 3.73 and make it worse. Maybe something in between.

Your 2.73s would give you the best highway mileage, but your high stall converter is a big gaz guzzler.
