Default Rear axle gear ratio??

Is there any way to tell what rear end my car had from the factory using the VIN number?? The service parts identification tag is no longer on my drivers side door. The car is a 94 Z28. How can I tell what rearend it has without the tag? Thanks.

With the converter locked in 4th gear, what mph are you?

273 = 80 mph
323 = 67 mph

What does your speedo go to? if you have a 150mph speedo you have 3.23's if you have 2.73's your speedo would only go to 115.
