Anybody gone from 2.73 to 4.10?

I Was wondering who on here have changed from 2.73 to 4.10 gears and how much of a change in acceleration and over all improvements. My car is acually quite pitiful with 2.73s. Anybod use 3.90s here? Thoughts??

no problem, you just must not know how to search or read......if you have an auto go 4.10 if you have a manual go 3.73, it will make a huge difference, best bang for the buck, no need to be an asshole

Not meaning to argue or be an asshole, spend alot of time reading, and half of its wasted reading retarded responses for some peeple to get a higher post count. I Do have a t5, and have seen alot of people saying 4.10 instead of 3.73, for a car not driven on the highway that much, street driven. There is not a whole lot of responses about how much better they liked or not, how much better it accelerated etc.

You are not going to get meaningful comparison numbers from anyone unless they have run both 3.73 and 4.10 in the same car and they have some numbers for each and your combination is similar to theirs. Everything else will be an opinion on why someone chose one or the other.

I have run 373 & 410 in the same car and also 390s! I ran out of gear in 4th with a t-5 before I crossed the line with 390s and 410s! But that was on nitrous! My opinion is if your gonna run a blower or N2O in the future go 3.73 with a manual! I currently run a 3.55 with a C-4 auto and a 150 shot and still pull 1.70 60ft & it goes 11.60@114! All stock suspension on et streets at 3500 pounds

I have 4.10's. Only thing I don't like about them is shifting every .7 seconds during normal city driving.

that's funny...
i trap 112-113 with 4.30 gears and 28" tall tire(same as 4.10s with 26" tall tire) on spray.
granted, i have to rev the car to 6k and the stock cam doesn't like it too much, but it's not that bad.
less gear would help, but i'm not "running out of gear", so much as running out of cam...

There will be a major change in accleration because you are making a major gear change. Acceleration goes up, fuel economy goes down.

My daily driver has 16 cylinders and 4400hp @ 1000 rpm....
