2.73 to a 3.73 would be a gigantic difference.. it'll feel like you packed on 80rwhp, I bet. And from a 55mph roll don't even think about it. My buddy has a '88foxbody pushing 409rwhp and 3.55 gears, my New edge is around 255rwhp(conservatively) with 4.10s, and I take him from a 55roll everytime. Don't fear the gear.

Wow, that much of a difference. Im so there. And I thought the sct tuner made a difference. Lol

Just make sure to do specific research to get more accurate numbers with a gear swap and your drivetrain options so you know what to expect! I love my 4.10s

[dolfin13]

yes i definately agree, the diffrence is incredible

[Mr. SoloDolo]

So dolfin13 what gears to u have?

[dolfin13]

i have 3:73s, I had a monte carlo ss with 4:11s and they were horrible on the highway anytime i went over 70, it felt like the ass end was dragging

Not to be scared about that.. My GT feels stock Cruising at 75mph with 4.10s.

So overall 3.73 are the best bet for an auto v6?

No. 3.73 is a "best" general jack-of-all-trades gear for manual. Autos need a steeper gear for similar results like a3.90 or 4.10. The RPMs will be similar manual3.73 and auto3.90. Some autos run 4.30 gears and swear by them. It is all preference.

i was wondering how much did your mpg drop from the switch?

[dolfin13]

it is all preferance, I dont like the 4:10s, in my opinion I think the 3:73s are the way to go, I have had them both, I like the 3:73s much better for highway driving. again thats just my opinion

I'd you don't do any serous interstate driving and you want the best performance, with an auto for me it's 410s gotta lovem

[dolfin13]

true

[Mr. SoloDolo]

But r both of you guys v6 or 8s?

[Dancobra75]

I've recommend the 410s to a few peeps with the six guns and they said they loved it

[Mr. SoloDolo]

Ok cool thanks
