C4 and gears
I am getting ready to put a c4 in my car. It has 4.10s. Are they to low? I do run 28 tall tires

really depends on were your red line is if your talking about drag racing.
Ideally you cross the line in top gear at red line - or this is what I always went after. If your talking about daily driving the car with some freeway use, even with a mod motor it will be running some good rpm. I think we have an rpm calculator in the Faq's section you can take a look there or I am sure there are some you can find on line. C4 final gear should be 1:1

Put your car in 4th gear and drive down the road. That is what it will be like with a C4

Why are you doing a c4? I would do the 4r70 and have overdrive. Believe you will be ok on your gear setup with a c4 though

I recommend 3.55 max for a 3speed auto that's also street/highway driven.
