I just read all of the old posts. I am bit of a car guy. What rear are you using? Whats Gear Ratio? I hope you stuck with the 12 bolt. I like my GM's all GM, no 9" unless I had to. Anyway just curious, I wish I had more time to work on my Camaro. Actually wish I could do a resto like this but with three kids under 5, thats on hold.
