here is a formula to help you
you are going to need to messure the roll of your tire do this by running a tape around the tallest part of the tire then deviding that by 3.14 you will also need an idea on what rpm you want to run and what speeds they hit at the track you run at

tire roll x red line rpm
--------------------------------------
336 x mph max speed
that will give you the final gear you need to run do you know witch 1st gear your tranny has is it 1.82 or 1.76?
