Easy question, Im after an easy answer. 3.9 diff gears or 2800-3000 rpm stall
I am wanting to hear from people who have them on their cars, either one or the other. I want pros and cons for each. I travel mostly higways, probably 80 % highways, so fuel economy on the highway is kind of important. 3.9's Pros: Shorter gear ratios Cons: Increase in RPM at 100 k's an hour Need to get the speedo re-calibrated May hit limiter on 1/4 mile Stall Pros: Faster takeoff No change in RPM at 100k's and hour (lock up?) Cons: Need transmision cooler Help would be good guys. My car is pretty stock other than exhaust and intake, so this is my next step. :dr_Evil:
