99 Corvette Vs 94 Z28 Last night I got into a race with a stock A4 99 corvette. It's not a convertable, but it has a removable top. Anyway, we went from 0-120 and I won by a car and a half. I was shocked and I thought the vette would pull me up top. Because we all know LS1's own top end. Anyway, the driver was a friend of mine. His dad just got this car and it's really nice. I pulled the vette off the line and it kind of stayed that way all the way to 120. So, top end it's pretty even. He didn't pull me up top and I didn't keep pulling him.
My friend and I were curious. How can we tell what gear that vette has in it. It has 1-2-3-D. Does that mean it has a 3:23? I know in the Z28's if your car has 1, that means you have a 3:23. If not, you have a 2:73. If anyone knows, i'm curious. Thanks.
By the way, what do you guys think about the race? What do those vettes run in the quarter? Mid 13's?

Find his SPID sheet and see what sites list for the proper RPO codes for the gears. I'm interested to see what the early production ls1 c5s run especially the automatics.

Where the hell did you learn that from. The only way to figure out the gear size is by the build sheet/ option list or by marking the drive shaft with the wheels in the air. Rotate the rear tires one complete revolution and count how many times the drive shaft turns. That is how you figure your ratio, not by looking at the shifter.

I have a 1st gear selector and my car has 2.73s.
You need to check the GU* RPO code to see what gears you have.
GU2 - 2.73
GU4 - 3.08
GU5 - 3.23
GU6 - 3.42
It's certainly possible that some of the 2.73 cars did not come with a 1st gear selector but that wasn't a universal rule.

Well, I have a 94 Z28 with the first gear selector and I have 3:23's. I guess I'm part of the majority. Sucks for your sister...I asked a tuner from a speed shop this question a couple days ago and he said the same thing. If you have 1st gear, your supposed to have 3:23's. At least other people have heard of this as well. I guess everyone else that agrees with me and the dealer is just stupid...
