help 8 3/4 gear

I agree with everone memike, sounds like you have a set of freeway flyers. Im gonna say 2:76 as well. My parts car has them in its 7 1/4. Its a /6 car & I was surprised at how it would scoot from a dead start. Nothing to call impressive mind you, but for a /6 car with 100K+ miles on it, I think it could hold its own on the highway.

Look at it this way. You'll be able to run 100mph down the highway all day long!!
