What Gear Ratio?

[InMotionJosh]

I am needing to order my new currie 9 inch for my 70 chevelle but am not sure which gears to go with. I am going to be running either a 408 or 427 LSX motor N/A. Its going to be backed with a 4l80e transmission. I need to figure out what gear ratio to order though. I plan to use a 28 inch tire and would like this car to be good on the highway and on the street. Id like a good balance of performance for both. i was thinking maybe a 3.42 or 3.55 would be a nice choice. Any thoughts?
