But the 9" offers a so much better variety to let you settle in to which might be the best for you. I don't know (along with a bunch of other things) how much you lose with the Ford set-up, but if you finally find one you can't pull, you can either go down a step, make more horsepower, of change the whole rear end to a different one with the same ratio that doesn't eat the horsepower up as much.
