Default L model type

I have a 1991 convertible how do I find out what type of L model it is? The car is all stock, how do I find out hp, gear ratio, torque.
i have the Marrone label from the dealer. I got lucky when I found this vette

Where or how did you come up with L model? Looking at the.options, I'm surprised no hardtop.

Your car has an L98 engine you can read the 91 specs here.

As far as gear ratio you need to check the codes on the SPO sticker in the console. All those codes identify the options your car came with.

Rear axle is the 3.07 since the sheet lists the $50 for the performance axle option.

As belairbrian mentioned, the SPID sticker that is located under the storage compartment behind the passenger seat and will tell you the options on the car. Once you have that you can download the free app “CorvetteDNA” and look up anything you want for any year Corvette.

On a different tread we went through d36 and gear ratios. Convertible used a 2.73 gu2 as the g92 performance axle. While the couple used the 3.07. Chevrolet was concerned about exhaust noise with top down.

Thanks Kevova, nice to know. The only convertible I have ever owned was my 64 fuelie and I loved that “noise” with the top down.

Great find in a great color combo, but then again I am a little biased.
