No way.
Why not? He made no statement as to what the car was intended for.

I want 4.10s and might go to 4.56s if the mood hits, and this will be a 10 bolt!

I just don't think 4.10's would be ideal for him. Man, 4.56's in a A4? Dang...good luck with that rear end.

Not an A4 now, TH350 and gas mileage will suck but it will get out of the hole!!

In actuality, 4.10s is what I will go to eventually!

Id say 3.42s. I drive at 90 alot and tach is at 3 grand with the 3.23s. Engine wouldnt last long at all with anything higher than a 3.42. If you are gonna race more than drive it 3.73s but I wouldnt go 90 on the freeway at all maybe 70 then I would get a daily driver.

Normally spelling is something I will not talk about, but it seems as though every thread that you create has the word "Witch" in it. You mean to be using the word "Which"

Get a torque converter.

If you have 2.73's, then go to 3.42's if you do alot of highway driving, or if its a strip car go wtih 3.73's. If your car has 3.23's now just leave them alone and get a converter.

If you are driving 90 mph, then 3.73's are def not for you.

I've got 3.73's in mine (went FROM 2.73's) and I tell you what, it sucks on the high. Just doing 80mph with converter converter lockedup, I'm doing about 2800rpm...stock drivetrain (cept rearend, ProGear 10bolt with 3.73's).
The car is much more responsive, but it tachs way high when driving and just puts a lot of constant strain on everything..specially since I've got the new cam. Valvesprings are probably pissed at me

I'm fixing to switch back to a 2.73 rear setup and a converter...see how that works out.

I started with 2.73's then went to 3.42s.
After a while decided to go to 3.73's based on all the praises on the boards and it sure made a difference even over the 3.42's.
But 3000 rpm at 80 mph put more wear on the motor than I was comfortable with.
Luckily I was able to afford putting in a Gearvendors Overdrive(.78 makes 3.73 into 2.91) and now my car is an A5 and tachs 2200 rpm at 80mph and 100 at 3000 rpm with 1 inch oversize tires.
3.42 is the most I'd go if you do any driving over 75.
