I cannnot remember my rear tire height
it is 285/19/35,stock C6 vette stuff. Anyway I am running a T56 out of a F body. I had a 3.80 and in 6th I was turning 1500 at 65. If anyone slowed me up it would start to buck. I changed it to a 4.10 and now I run 1750 at 65. Much,much better. I can still run 40-45 in 1st turning 7000. My gearing is perfect for me and my motor combo. My LS1 idles at 900.
Hope this helps.
