So my car is at the speed shop right now having MS3 cam and tci 3500 Stall put in right now I have 273 gear trying to decide weather to go to 342 or 410gears but after reading the first post on here Im kind of confused, what would be better or am I only gonna gain .1 in the 1/4 like the post says but I' assuming tht info is with stock engines I've had 410's in an A4 before but it had a stock converter and cam it was nice but they also broke
I have heard the 410's are very weak in a 10 bolt compared to 273 or even 342's...lets here some opinions from some ppl with personal experience on this or expert knowledge.
(And getting a 12 Bolt is out of the ? for this year). I also have a girdle to go on if it helps any. Thanks

gm muscle still runs his stock 2.73's. but i would do 3.42 that is what i am going back to. i just installed the ms3 and a yank pt4200, i have 3.73s right now.

I just put some 3.42s in my uncle's lt1 and the difference is night and day going from a 2.73. However, I rode in my friends 01 WS6 Trans Am last week and he has a 3800 stall and 3.73s. That thing is a beast. I would recommend the 3.73s if milage is no concern, but 3.42s are the best all around gear for an auto in my opinion. I don't think the 4.10s would hold up too long to a magic stick cam and a stall.

I have 3.23 gears with the Magic Stick and a 3500 stall. I am going with 3.73s to try and keep the engine in its powerband. I also run 28" tall M/T slicks at the track. I guess with a 26" tall tire would better suit the 3.42s.

If your staying N/A and want some killer numbers, your going to need gear and converter. N/A with 3.42s it is going to be hard to get the car out of the hole good, it would also really like a 4000+ stall but I think your 3500 stall will do the job. I would personally start by trying to 3.73/26" gear and tire combo. I think that would give you some nice numbers and be very street friendly.

OK Well If I go with 342 then you ight as well call them 373's there aint really any difference.How will my car run with the 273's that are in there now? I know there not prime for racing but will they be horrible or what?

The times in my sig are with 2.73 gears. I'll have some 1/4 miles times tomorrow if the weather holds.

Were they noisy?
What was the power difference across the entire powerband?

I am having the cam installed right now, what the powerband on it usually? Also with that 1/8 time what would the expected 1/4 time be? I hope to be in the id 11's is this realistic?

With a half decent 60' you should be able to run 11s easy. You could always put alittle nitrous to it.
