M10 with 3.73 diff?

[Smelser]

I just bought an open small case 4.10 for my racecar, Im taking out the LSD 4.44

both small cases. When I get to the back of the car, I will cherck for mounting, if the 4.10 goes in ok, I will sell the 4.44 , that will give ya some pep!

The 3.91 is a small case, but the 3.73 is a medium case. I thought you could mount either?

I do have spare small case cover, and medium case cover..

I think you have to change more than just the diff , perhaps someone who knows more about smallcases will chime in. It might matter if you have discs or drums in the rear. The reason i asked is 4.10s are more common in small case size,

I would rather have a 3.73 LSD than an open 3.91. Its a pretty small change, but it will be slower. What you want is a 4.10 LSD, i'll see if i can find another one.Are you small case or medium case?

Nope. Just make sure your turbo is functional.

I searched and found a lot of nothing..

Will an M10 feel really slow with a 3.73 LSD? I have a 3.91 open and I am wondering if I should swap them. Is the 3.73 too low?
