I'm restoring a '69 2+2 and while it has 3.31s because it's a manual, I saw that the default axle for the LS1 427 (335hp) with the TH400 was the 2.56 rear end. That's a steep setup! But 3.08s with OD would be significantly steeper than that even.

Assuming a .7 OD you'll wind up at 2.61:1 which is darned close to that 2.56:1 number!
Dave, BIG difference in torque between old51sedan's 6cyl. C10 and your 2+2
