No, but if you have a Z06 or a 6speed coupe or vert, it is always a 3.42. You will need to look at the options decal to see if you have the optional 3.15 (option code G90/G92) if you have an auto tranny.

How about a little more info? Auto or manual, stock or modified. The gear ratio if stock, is coded in your RPO codes. What year car are you asking about? The ratio can be determined by driving at 75 mph in 4th with manual, 3rd with auto and divide rpm by 1000. So if you run 75 mph in 3rd with automatic and your rpm is 2730, your gear is 2:73

If you are going 70mph and rpm is 1500 and a 6speed you have 3.42 gears. A Z will be different because of the gears in the trans.
