Default rear diff changes in size

Hello I want to get more torque off the line and everything im reading says get a larger rear dif gear.

Does anyone know what RPM i'll be at doing 60pmh using a 4.77? 4.56? (in 6th)

trying to figure out how bad my MPG will be impacted.


i did some searches but couldnt find anything

Cheers

If you want to simulate what the 4.77's would be like on the highway, just run your car with stock gears in 5th gear. The difference between the two is less than 3%.
