Default Gear ratio with TH400?
What rear gear ratio are you guys running with a th400 transmission? I'm running mostly 1/8 mile. Rarely do I run 1/4. Thanks

Here is a good gear calculator.

I run 4.10 with a 28x9 Pro Bracket Radial.

Do you drive the car on the street at all?

Not very far. I'm thinking about going with a 4.56

You should be able to use a gear calculator to see what your RPMs will look like without converter slip.

Standard TH400 gear ratios are 2.48, 1.48, 1

You'll just need to know what tire size.
