I am pretty sure the standard gears on a 5.0 are 3.31 I have never heard of of one with 3.15 but if for some reason you have that gear I would for sure change it to a 3.55 . I have 3.73 and they are fine for now but once I supercharge I will go to either 3.55 or maybe even back to 3.31 after we do the math on the tire height, hp, torque etc - since I do not want to have to shift to 5th at the back end. Right now I am at abt 7400 rpm and 118mph in 4th gear at the trap with 420rwhp needless to say these gears will not work with a supercharger putting down over 550rwhp
