Welcome!

Nice to see more local folks on here!

If your car still has the original trunk lid, you can look up your rear gear ratio on the RPO label on the underside of the lid.

The rear end codes start with G.

Here's the common G-body rear end related codes...
GH2-2.29 ratio
GM8-2.56 ratio
GT4-3.73 ratio
GU1-2.41 ratio
GU2-2.73 ratio
GU4-3.08 ratio
GU5-3.23 ratio
G72-2.14 ratio

G80-limited slip differential

A 13 second car should be easy to acheive with a simple small block Chevy. What motor is in the car now? V6 or V8?

Welcome to the forum! If you've got the original 307, it's gunna be some work getting it to 13's. Looks like you'll need a new engine, I agree with Blake, go with a SBC. You'll need about 350-400 hp on the motor with correct gearing to run in the 13's.

Well, you don't learn anything if somebody else does it for you!
