I think your Cobra is more of a street car, right? If so, I would go with the 4.10's. Good acceleration, but not overkill for the street/highway use. Plus, it would be a hell of difference from the 3.27s that are in it now. (I believe 3.27's were the stock gear?) 4.56's would be great for a strip Cobra or at least one that sees little street/highway use. JMO.

As for the gears working w/an 8.8 IRS, the Ford tech that is doing the install for you should know.
