69 Z/28 Day II Project (Air Force Brat)

With a 2.56 first gear, a 4.56 rear gear and 28" tall tires you'll have a starting line ratio of 11.67! 4.11s would give 10.52 which is probably a little more manageable. I'm nowhere near an expert on this but I think the 10.50 range is where you want to be with a light weight Camaro with a 3.50" stroke.

Agreed Chuck. I looked at the calculators after posting that combo the other day to help decide if I was going to order a close-ratio (.220 first) or a wide ratio (.256) trans. I have now decided on the wide ratio and will likely go with 4:10 gears.
