Are you going to try to use the same gears at both tracks? You'll have to compromise some if you are, unless you have two sets of tires with significantly different circumferences.

Assuming a 350 street stock type motor:
1/4 mile track = 6.75 - 7.25

3/8 mile track = 6.40 - 6.75

Should get you in the ball park.
