I had 4.11s on a base 6 speed (M6 gearing) and liked them
Now with the M12 in my car with 3.42 (like having an M6 with 3.90s) I like it too.
You can't go wrong with either, both will make the car feel a bit lighter, more snappy.

I always heard the M12 was like one step up on gears - never heard 3.42's = 3.90 with M6....

What about when you have a cammed car? I have a Torquer V2 and of course the headers and all the other bolt ons that go along with a cammed car. I know you have to try to match the gears with the power band of the cam for best results. Are the 4:10 too much or would 3:73 or a 3:90 be better?
Not rying to hijack, just didnt want to start a seperate 4:10 thread.

I have a stock motor 03 Z with long tubes.With my stock 3:42 gear, ran in the 11's
Car came stock w/3:42's. I installed a H/D 3:90 a year or so ago & could hardly tell the difference in performance/seat of the pants.
First time I got on it with the newly installed 3:90's I knew right away that I should have jumped to the 4:10's

I gotta ask. Have you ever had your car at top speed? I'd bet 98% of all vette owner's never drive any faster than 120.
Don't fear the 4.10 gears. They cost the same as any other gear change.
Motive gear seems to be the main provider of gears for our cars.

4th gear - depending on your tire and driving abilities, you will have to raise your limiter or get a taller tire.
On a cool day in November of 2009, I went to a track rental. My first run I hit the limiter that was set at 6400. I had my tuner raise it to 6600. No more problem.
I was using 25.7" tall Hoosier drag radials and trapping 119 - 120.

I had 4.10's with a M12 tranny and hated it. To much gear for street driving and a real PIA in traffic.
I think the 4.10's are a good fit with the MM6 tranny, but not the M12 unless you're really into drag racing.

You have to kinda work to get that with 3:42's; I'm doubting thats the 4:10's are still getting that good of mileage. Also, I'm pretty sure theres some tuning work with regard to tuning for the MPG to be accurate when gears, injectors, FI or a cam has been installed. Otherwise the PCM still uses the tables for stock gears, injectors ect; I've seen this somewhere else in the scan and tune section I believe.
