How to tell what gear ratio I have?

It's a 4t65e hd from a 02 regal 2800sc.

2.93.

Thanks is that a good gear for the 1/8 mile or is there better and do I have the limited slip?

Sure it's fine. You'd likely notice zero changes with a 3.29 trans in the 1/8th.

No factory trans has a LSD I think. You can spin both tires with ease though, just need enough power.

Foot brake it to 2000-2500 and roll into it and pin to the floor once you know it's not going to break em loose.

Righto thanks.

2/10s quicker in 1/4 mile with 3.29s

Sadly there is no hard data on any of that.

It's all about the driver and always will be.
