look at your drive shaft and count. if you turn your tire 1 revolution and the shaft goes around 3.5 times 3:55:1 if it goes around just over 4 times 4:10:1 thats how 2 calculate ratio

there is NO way in hell it has 4:10s in it, 4;10 with a 26" tire would turn about 4k rpms. my car with stock 3.23 gears turned about 3200 at 70mph. Sounds like this car has the 2.73 gears.

Check on here http://www.f-body.org/gears/

If you were spinning 3200 at 70 then your car wasn't shifting to 4th or something. 3.23's with 26" tire puts it at 2050 rpms at 70 mph. 2.73's you'd be at just over 1700 rpm.

OP, I would agree with 4.10's

Your car had something else wrong with it. In a stock set-up, 3.23s turn 2k at 68 mph. Thats a fact. Anything other then that and you have something else going on. Converters not locking up will show about another 400 rpm on top of normal. So thats always something to factor in.

While on the highway doing 70 take the car out of overdrive and put it in drive, what your rpm's read is what gear you have.

well its been a while since my car was stock, I thought that was the RPMs it turned, now im not sure. But my car did have 3.23's in it for sure. The best way to tell is like said above, throw the car on jack stands and spin the tire 1 turn and count how many times the driveshaft spins.
