I love the 3.55 gears in my '89 GT (5 speed) because they're perfect for the near-stock powerband. I shift a little over 4500 (right near peak horsepower) and it drops right down to 3000 where it's making peak torque. On the freeway, going 60 the tach is at 2,000 rpm and you can feel it pull pretty hard at 70+. I've gotten my car up to 135 with little trouble. With a near stock engine with mild bolt ons they're my pick, although most people recommend 3.73's for a stick. With an auto you may want to get 3.73 gears for a near stock car, and i don't think that it would kill gas mileage too much, it also depends alot on your tendancy to gun it.
I get ON AVERAGE mostly city driving too, about 19-21 miles per gallon.
