Was wondering if I could get some ideas on what gear to go with. I've got a 97 GT 4.6 5spd, 126000 miles on it. It's still got the stock 3.27 gear. The car is basicaly stock other than 70mm tb and under drive pullies. It's not my daily driver but I do enjoy driving it as much as possiable. I'm sure I don't want 3.55's and I'm thinking 4.11's would kill my fuel mileage. I'm kinda wondering 3.73 or 3.90's? I guess what I'm asking, how much worse will the 3.90's hurt my mpg over the 373's and what rpm's be turning at 55-60 mph? Any HELP would surely be appreciated. THANK, Budd...
