Don't forget about the torque multiplication of the torque converter in each gear, especially on the starting line in low gear.
I can remember many stick shift modified production cars with very small C.I. motor running 2.98 first gear ratio and 6.17 to 7.17 rear gear ratio for the 1/4 mile a long, long time ago work
I shoot for the lowest starting line ratio I can run that won't spin the tires on the line up You may need to experiment some on your car to find what works best for you at your track shruggy work
Good luck scope
