Wasn't just for gas mileage on the highway, but for the way it downshifted at speed too...anyway, guess it depends what you're shooting for...but they don't really really suck on a stock car for either.

well, ive got 3.23s and i go to the track every once in a while and am definatly going to get a stall after headers are on the car, and i would recommend the upgrade to 3.73s cause how ever well a stall makes ur car with 2.73s, it will be that much faster with a stall and 3.73s. Also, if u wanna keep those gears i would recommend getting a bigger stall.
I used 2.73's with a 3600 stall and turned 1.6 60ft's. The only problem with that is- Everybody knows that a stock 10 bolt is a piece of crap. But with 2.73's it puts all the accel pressure on your transmission not the rear-end. I went through 2 transmissions with my 2.73's and when i changed out to 3.73's I broke my rear after only 3 good hard launches.

well, ive talked to sponsors and they said for a street car to just go with a 3200. its never gonna see the track anyways. its a daily driver. i want something nice and tight. i dont see how i can possibly hook on a 3800+ size stall on the street anyways.

I would get the converter first and then see what you think about your gears. I did the opposite because I hated my 2.73's around town. But my car has been hard to launch with the 3.42's. I'm beginning to wonder if I might do better with the softer launch of the 2.73's.
I hated my 2.73's when the car was stock. Absolute joke from a dig. I was going to get rid of them and swap for a 12 bolt or S60 ASAP but... After the FLT and the Vig 3600 plus a tune.. whole different story! It knocked .6 of the 1/4 mile and it cuts 1.7's on Dr's with ease. I'm happy enough with the 2.73's now to forget the rearend for now and go with a cam only and some headers as the next mods.
