05-07+ Auto's are 3.31
05-06 Manuals are 3.55
07+ Manuals are 3.31 (3.55 optional)
i personally am going with a 3.73 or 3.90 for my car since i my car is a daily driver with some track time, but 3.73 are the best all around set, 4.10 for manuals and 3.90 for autos are the max from what i have seen

I don't understand some of your mileage estimates. I have 4:10's and get 18.5 - 19.5 in a lot of stop and go traffic. If I can run around 60-65pmh, I can get up to 24.5 mpg average over a long distance. How are some people getting only 15 or even 12? Granted I can get it down there if I beat on it, but are you guys driving that hard for that long?

That's reassuring. I have a Stealth with a 3.0 V6 and I get 22-23 with it. It's EPA rating is almost the exact same as the GT and the Gt has 120 lbs/ft and 80 horsepower more on regular fuel with less driveline loss. (Either that are the stealth is overrated.) The Stealth requires Premium fuel, too.

My '00 Crown Vic w/ 3.55s (225/60R16) gets 11-13 mpg in pure city/stop-n-go driving. I've gotten as low as 9-10 mpg though. The Vic gets a max of 18-20 mpg with pure highway driving and I have never been able to break 21 mpg. I managed to snag 23 mpg with the 2003 E-250 w/ 3.73s (225/75R16) and the 5.4 2V V8 in pure highway driving. That is also when I nailed the speed limiter at a blistering 89 mph... It revs about 200 RPM slower than the Crown Vic on the highway.
I haven't taken long term gas mileage readings with the Stang yet, but I have high hopes for it because of the VCT, CMCV, 5-speed manual gearing (only 2000-2100 RPM at 75 mph), and reduced mass and aero drag.
