I love my 3.73's on the highway. You'd be at about 2300 rpm and the engine will will sound so sweet. Fuel economy will barely drop on the highway and city will be a little better.

3.73s were perfect for me in my daily driving, with the addition of a blower it was even better... except at the strip where I'd be better suited with stock gears or 4.10s on stock wheels just because of the need to shift just before I cross the line.
My morning commute NA was slightly hilly and my fuel mileage actually increased under 55 mph because I could stay in a higher gear through the hilly area. Highway things didn't change too much staying under 75, but speeding a few mph over did net a bit higher RPM and noticable mpg loss. It's worth the tade off though IMO whether you go with 3.73s, 3.93s, or 4.10s

I have had 3.73s for 2 years and loved them. Now I have 4.10s going in. I would say if you are going to stay N/A go for 4.10s but if you are going F/I down the road go with 3.73s.

3.73 make a great choice for a daily driver
I've had mine for about almost 2 years and about 35,000 miles...I think they are the prefect choice for a street car that spends any kind of time at all on the freeway

I loved my 3.73s when I was naturally aspirated. They're still great gears with a blower, but I'm very close to running out of gear at the strip, so I'll have to throw 3.55s in there eventually (or run taller tires).

I have had my 3:73's for about 60,000 - 70,000 miles now and have had no problems. you will enjoy them. oh and if I drive right I can get about 23 MPG out of it.

I agree with all the statements. I also ahve 3.73's. I take several trip on the highway and I still get anyway from 24 to 26 mpg constantly at 70mph. When I had my X-Cal tune on, I once got 27.3 mpg. Not bad at all. People ask me what type of milage I get all the time. I tell them and they just look at me. I tell them that the days of V8 sports cars getting terrible gas milage is for the most part a thing of the past. A guy a go to church with has a 08 350Z. I asked him about his gas milage. He told me he got 19 mpg. He also said he has a lead foot. In 6 gear his car is taching at 2700 rpms at 70 mph. My car at 70 is taching around 2170 according to my Scan Gauge2. Pearl02.

I have 3.73's and hate them in a mod motor..... they are no where near enough gear. My car is not a daily but a weekend toy so fuel consumption is of no concern. I can say that my 3.73 car gets the exact same mileage as my 4.30 04 gt used to. If and when I get time/money to swap, 4.30's or bust here...... Don't fear the gear...
**this is my personal opinion and experience so take it for that**
Oh, if you plan on going fi then 3.73 or 3.55 is a good choice as you don't want to run out of gear or have to worry about a 28in tall tire.

I couldn't imaging driving my car everyday with anymore gear than 3:73s...I'm sure 4:10's are fine for some, but for a freeway driven DD they are too much...heck half the time first gear is damn near useless with the 3:73s

First gear is waaaaay to long with 3.73's. 4.10s heck, 4.30s now thats a FUN first gear. 1.9 sixtys on street tires with 4.30's here. Like I stated above, (with city driving) my mpg is the same if not a bit worse in my 3.73 gear car as my old 4.30 gear car. And I KNOW my 98 is lighter than my 04 by quite a bit (alum block, ac delete, sn's are a bit lighter than new edges).

Exactly. Personal preference. The real question is whether performance or economy is goal here.
