Typically there were 2 ratios. The standard was 3.23 If buyer paid extra, and there is a code for this on the inside of the glove box, then you could get a 3:73 limited slip. Trade off for better mileage or more off the line. The '94's did not have the vortec motor, so they were lucky to have about 200 hp at rear wheel. A chip helps 'a little' but from then on it is premium fuel, and lots of it.

Probably if you raise both rear wheels off the ground (blocking the front) and turn one, and if both turn in the same direction, it is most likely the limited slip with the 3.73 ratio.
