You should not notice a dramatic change in milage.

atleast go 3.90's or more with a 6spd, I only went 3.90's because I spend 90% of my time on the highway. The 3.90's were noticable, you most likely wont feel much of a change with 3.73's. most will tell you go 4.10's, which there are time I wish I went 4.10's then theres times I'm glad I didnt go with 4.10's.

I had 3.90's in my 10 bolt and wished I went steeper. I put 4.30's in my 9" and love them. If you are going to swap gears make it worth it. Go at least 4.10's. You rpm's will be up 350 rpms from stock at 75 MPH on the highway.

3.73's are a huge waste of time and money with a 6 speed car, unless you have extremely high horse power #'s.

Gas milage #'s with 4.10's you might lose 2-3 mpg at the most.

In town gas mileage with 4.10's sometimes actually stays the same, as you can use 3rd gear almost all the time. Bob
