[QUOTE="Richard L, post: 1030329, member: 52972"] Most effective gear ratio???? Depends on what you are wanting. Lower gear ratios like 4.10 are 4.29 better for acceleration but give less MPG. Higher gear ratios like 3.55 and 3.73 are better for higher speeds and better gas mileage. In the end it boils down to what you are looking for...stop light to stop light acceleration or better MPG on the highway....For just raw power, you need to know what RPM your engine will give you the most HP and how that equates to MPH. If the vehicle is only going to be used for racing (which I doubt), then the lowest gear ratio will always give better acceleration, but your speed will be limited by your engines maxiimum RPM. If you want a daily driver that compromises some acceleration for better MPG's, then I would not go much over 3.73...which sounds like where you are at now. ...Rich [/QUOTE]
