Stick with the 3.73's , the new 4000 converter will make a big difference !!!

Ya stay with 373s the 410s will make the rear even weaker. The 4000 stall will be a big difference..

do u think ill run out of gear ?or can i just raise my rpm

ya i never thought of the rear end gettn abused by lower gears.i dnt plan on upgrading the rear end right now

was wanting to go with 410 cuz my buddy has 410 in his camaro and wanted to trade whole rear ends cuz his car is mainly stock

Dont waste your time with the 4.10's , the A4 transmission has a very steep first gear . The new converter is going to hit your tires much harder , and like ( 1Badws6 ) said your rear end dont need anymore stress on it ! your 60ft will most likely be in the mid 1.5's , hopefully your tires are up to the task lol ! good luck it will be fun.....

Did you get to install your 4000 stall yet. I bet you can feel alot of differences..

I ran 4.10 gearing on the GM 10 bolt along with a 4000 stall. Best 60ft n/a was a 1.48. At the same track outing, I hit 1.39 w/175shot out of the hole and the 10 bolt took a dump. Overall opinion, 4.10 gear and 4000 stall is a good combo. I still run the same combo, but with a Strange S60 rear end.

Stick with the 3.73 IMO it will give you room to grow.

I myself have a 4K converter and 3.73's. While I wouldn't change my 3.73's for 4.10's I wouldn't be opposed to trying them if I still had 3.23's

Would 4.10s on a stock stall not be better for someone wanting to avoid a bigger converter? Assuming DRs are on the car of course.
