Which is better 4.10 or 3.73 LSD?

[///M42 sport]

heres my 2cents

economy on highway = 3.73

If your doing 50miles roundtrip to work its just going to add up on fuel costs.

I have a 4.10 on my m20 and cruise at 70. and avg 25-28mpg. Why get this when you can easily get better mileage from a 3.73?

Also no you dont get to your destination faster cruising at 80 on extended road trips. The more gas you use, the more you fillups you do.

I think its funny when I see the same cars fly by at 80-90 on the highway two or three times. All the while, I've have yet to make a fuel stop.

No "s" just a standard diff. How hard is the process of putting a new diff in?

"S" is limited slip.
