exactly what I said, the wide ratio is only 3-4. I figured that out when I was in high school, I used the wide ratio with 3.90s because once you got up to speed, the 3-4 drop was nothing. The close ratio trans is for road racing when you are constantly shifting in and out of 4th at speed. For drag racing you need all the starting line ratio you can get up to a point.
