Go with the 3.08 or 3.27 if you drive it on the highway at all. This will be plenty unless your cam is too aggressive. Otherwise go with a 3000 stall converter and 3.73 but dont go more than 1/4 mile at a time ;-)

I had 3.27 with a C6 in my CR and it was a good compromise. Tom Wells has a C6 and uses like a 2.93 but he has a 521 BBF and still spins the wheels past highway speeds. If you decide on 3.08 I will send you the ring and pinion if you pay shipping. If you need a traction-loc for 31 splines I have that too.
