I'm running 3:73's with a 200r4 and 27 inch tall tires and love it. Perfect combination to me. I haven't run fuel economy numbers yet, but I'd venture to guess high teens to low 20's at least. No tach on the car for rpm's, but calculator says 2100 at 70 mph. Goes into overdrive around 46-47 mph, and does not lug. Engine is a 389 that made 400 hp and 460 tq on the engine dyno.
