Stock tires?
Anyway with 3.23s 70 is about 2100rpm.
70@2200 would be equivalent to a 3.42 rear end, but obviously this isn't the best way to calculate your gear ratio. If your sure it's stock, look at the codes in your glovebox.

GU2-2.73
GU5-3.23
GU6-3.42

My buddy had a 95Z with a stock converter with 3.73s and he turned 2500 at 75mph.

Are you sure the rear gear hasnt been changed?

275-40-17 is the tire size and im pretty sure its stock gears, it only runs a 13.8 1/4 which is pretty slow

275/40/17 is significantly close to stock (245/50/16) size for your car so I wouldn't factor in tire error (IIRC it's less than 1% @ 70MPH) I'd guess you have 3.23s but look in your glove box to ensure.

[95z28ss]

ok i will

[95z28ss]

not in the glove box or the door

i went to the dealership and they said i have 3.23 stock but i double checked today and im running 2300 rpm at 70 and 2500 at 80

it wont say what gears you have, but there will be a a bunch of rpo codes, look for one that has GU and a number like GU2 or GU5, I think those are the codes for the rear gears in the auto's. I believe the GU2 is 2.73's and the GU5 is 3.23's, someone correct me if I'm wrong.

I would teake the diff cover off and look. If its stock or aftermarket, it should be stamped on the ring gear somewhere.

if it's stock gears you have 3.23's. mine is a 1994 and my rpms and everything are exactly the same. Also I had a guy look in my glove box because I didn't know what my gears were and then I also looked them up. You have 3.23's

[95z28ss]

ok thanks so i guess im going with some 3.73s then

Edit: Nvm you're referring to yourself being owned. I wasn't trying to own you, just saying I already covered it. You're absolutely right though. I posted the 3.42 RPO code as well because who knows, the car could originally be a M6 car swapped to an auto. It is 13 years old, who knows.

yeah, I pull off a good one every now and then, and that commercial was pretty darn funny.
