Rear End Gear Ratio's?
Hello all, gear ratio question for you. I have a 91 Coupe L98, 6 speed trans. How do I find out what gear ratio is in it? Any help would be appreciated... Mike

Look for your build sheet. I have a 86 and mine is behind the dirver seat compartment. One of those codes is your gear ratio. My code is G44 which is a 3:07. Hope this helps.

My 93 has a list of RPO's(Regular Production Order?) inside the center console. The Forum has a list of RPO's somewhere? If you think it's been changed then you need to jack it up and rotate the tire 1 full revolution and count the number of revolutions the pinion yoke makes.

I have a local guy at a "corvette shop" telling me that the way to really wake this car up is to change the gears, he says a set of 3:73's are the way to go. Is it worth the money to go from 3:45's to 3:73's?

That was my thinking, they want close to 2g's to do the job and if I'm going to spend that kind of $, it better throw me out the back hatch when I stand on it.I don't think 3:73's will do that...but 4:10's might and as you said, I always have 6th gear to cruise with. What didn't you like about the 3:73's?

6 speeds are very different. Most seem to respond well to them(and the 4:10's)
