Man I still think that sick lol. I just saw on a Camaro site that my car was factory with 3.23...
"2.73 - These do not come as factory equipment on any V6 F-Bodies, though they are offered on some V8 models. Gears this low are designed for two things: sustained high speeds (very, very high speeds, like Autobahn-style) and for long-distance highway gas mileage. An F-Body equipped with 2.73s will have a very low rpm at highway speeds, and coupled with a 6-speed transmission they are excellent for long-distance cruising. Low-end acceleration, however, is terrible. The engine has to struggle to get the wheels to spin, so do not plan on getting 2.73s if you enjoy actually moving when you hit the gas at a stoplight. V8 owners can get away with running 2.73s because they have obscene amounts of low-end torque, but there is no real reason any V6 owner would want these. Contrary to popular belief, a V6 equipped with 2.73s would actually get worse mileage than stock if doing any sort of city driving, because the engine has to struggle so hard to get the car up and running. That alone cancels out the low-cruising rpm advantage.
3.08 - These come as factory equipment on base model automatic 3.8s. These gears are great for fuel economy but offer very sluggish acceleration. If you are even remotely interested in performance stay away from 3.08. V6 owners have been known to drop from 15.8 to 15.2 in the quarter mile just by switching from 3.08 to 3.42.
3.23 - These come as factory equipment on all 3.4s and on manual 3.8s with or without the Y87 performance package. Since the Borg-Warner T-5 manual transmission has five gears compared to the 4L60-E automatics four, manual owners can get away with using this lower ratio. For the majority of manuals these gears tend to work best: they combine a good mix of acceleration and very strong top end. They are, however, still a bit low for most automatics.
3.42 - These come as factory equipment on automatic 3.8s equipped with the Y87 performance package. 3.42s are probably the most popular gear ratio for performance-minded V6 owners because they offer great acceleration without killing too much top end. If you have an automatic its pretty safe to say that 3.42s are your best bet. Some manual owners have switched to 3.42s and have had good results with them as well.
3.73 - These do not come as factory equipment on any F-Body. 3.73s offer arguable gains. Low-end acceleration is excellent and you can be assured of quicker 60 foot times with 3.73 gears equipped. However, the 3.8 V6 in naturally aspirated trim tends to fall flat on its face in higher gears--fourth for manuals and third for automatics. 3.73s will put you in those high gears quickly, so then when you actually get to the top end your acceleration will be decreased at best, butchered at worst. Additionally, with 3.73s equipped your engine will be rev quite high when driving at highway speeds, typically at 2500-2800 rpm. For prolonged periods of time this can cause excessive engine wear and terrible gas mileage."

273 DEF! did come in few v6 camaros,,, I KNOW they did in 93 had alot of friends with the issue in hs... then we all got v8s so whereever you got that is wrong,,, but idk chekc your rpo code and then google it, it will tellyou the gear size
@ dark knight, nice kill. would have been awesome to see that one going down.
as for the gears, my sixxer has 3.42's in it. Which are decent for taking off, but still return good mileage. i wouldn't mind moving up to 3.73's or 4.10's if i was keeping it.
the very least he should do is 3.42's if he is looking for anymore take off. i would say do 3.73's

I know my car either has 2.73 or 3.23 gears. Not sure exactly what. I want the get 3.42 gears. Maybe 3.73's. Opinions? Options? I would like to have rear disks and posi as well

A lot cheaper way would to just get an LSD and then buy the gears later. I just got an LSD for my v6 for 100 bucks. 3.73 gears will be about 150, and the speed calibrator will be about 130. A whole rear end would be a lot more, and youd have to pay for installation as well, which would also be alot. And if you get a rear end from a junk yard, youd most likely have to get new brakes fand rotors.
