I currently have 3:23 stock z28 gear. I was wondering if i run a 28" slick on my car what will my gear ratio be down to?

Assuming you have a 26 inch tire now, revised ratio would be about 2.99.

Pretty basic math - ratio the circumference between tires and multiply by existing gear number. Circumference is Pi x diameter.

Be careful with stock rear end with slicks or you may need a new one.
