no matter what get the 4.10's...ppl say that with a s/c 4.10's are no good to be honest it is the best thing i ever did to my car.... so for whatever your set up is i would say 4.10s all the way

I love my 4.10s. They are tons of fun to drive with. Even with my S/C they're not too much. But if I was gonna do A LOT of freeway driving I'd probably switch them out for 3.73s.

Good article that makes a case for 4.10 gears. Its what helped me make my decision.

I have 4.10s in my automatic and love them. My mpg went up in the city and down on the highway. If you do alot long distance trips you might want 3.73. I drive 10 miles to work eachway on the highway and am happy with my 4.10s.

3.90 is the best all around gear for these cars IMHO.Very glad I went with it.

4..10or4.30s i drive long trips and still get 20-25 mpg (1500miles= round trip)

When I bought my cobra it had 4.56s in it and it was sick but sucked alot of gas on the highway. The speedcal that was installed broke so I took it back to the ford dealership and they changed the gears back to stock. It was depressing going from 4.56s back to 3.27s. I'd say get 4.10s.
