Gears

I recently built a BB 440 which dino at about 527 horse at 6500 RPMs. This motor is going into a street car. I was wondering if anybody had an idea of what some good street and strip gears to put in
Sorry but that is such a loaded question.
It all works as a package. The cam was picked for Auto, manual or dyno?
How heavy is the car, Intended use? Rear tire height?
Wow! You built (or bought) a big a$$ engine. Without the other stuff, you built an engine for a guessing game.
Please let us know the particulars and we can help you with your gear ratio question.
If not this is a wasted thread.
