Looking for some help with final gear ratio. What would you guys suggest for a final for a 3/8 mile track and a 1/4 mile track? Any help will be great.

They are 27.5 X 8.0 Hoosier A40's. Tires measure 88 inch roll out and 13 inch from center of wheel to outside of tread.

17j, if my cams operating range is from 1600-5800, do I want to turn 6500 RPM?
