can anyone help with this question on gearing

[LONGGONE]

I have two friends that have C5's with automatics in them and one asked me to see if he can get some help with his question.

Here goes.

Can someone tell me the gear ratio of a C5 auto trans 4L60E
1st 2nd 3rd 4th or is there a chart anywhere to determine given rear end gear an stock height tire, what the speed would be in each gear at 6700 rpm for an LS1 edited motor.

Thanks
