    Bob, I seem to remember a thread on this subject from years ago and as well as I can recall, it seems the consensus was in the 3.50 to 3.70 range as a reasonable balance, so you're choice of 3.55 would seem to be right in the ballpark.

    The 3.55:1 ratio is very popular in hot rodding and for your application seems about right also. But I think this is a Ford ratio. In 10 bolt rears chevy has 3.42:1 and 3.73:1. I would lean more towards the 3.73:1 with your over-drive.
