[Super73]

There is a pro brake going in the trans. I tend to think that the added TQ will make up for the gearing, but I don't know for sure. I know with 10* of timing out of the hit (which results in about 80ftlbs of TQ) the best 60' I cut was 1.67, but adding the timing I went 1.59.

Most everything being the same, with a 3.73 gear, slightly less power and weight, on kill I cut the same 1.67 60' ... A 3.73 gear and 30" tire would be the same gearing in 1st as a glide with 4.56's and a 27" tire.

Or I can look at it like the new combo being 4.56/30" tire and glide would be like a 4L80E with a 4.56 and a 40.5" tire..
