The way I look at it if u wanna race it and have some mods on the car 4.10's the only way to go.I changed to a c4 last fall and run 26 et streets,the thing tachs 3000-3200 at 60mph.I don't care about mpg it's my race car!I loved the gears with my 5 speed,cruise rpm was about 2200-2500,if u want 50mpg buy a honda(just kiddin about the honda)
