has any one switched from 3.23 gears to 3.73 I am just curious on how much an improvement I will notice. I know I will be getting more power but, what track differances will I see. right now with no traction I get 13.9s and on the street I gan pull on mid 13 to low sec. mustangs. Will I hit low 13s? I am only doing this because I am going to install another rearend and will look for a 3.73 to replace mine

 

I changed from 3.08 to 3.40 on my p/u and i put a locking differential ona s well, its quicker and plants the tires a lot better, better take off. Also better in the mud..but that wouldnt really concern you, i hope.

 

well its spring and in WI as much as you try your daily driver hits the mud.
