A 10/12 bolt setup eats less hp, though, due to the pinion height, and it's quite a bit lighter...the GM units have lived beneath some pretty stout stuff...so if you're within the limits of a good 10/12 setup, you'll be ahead of a comparable 9-inch setup. But if you're talking crazy amounts of HP (and hooking it), the 9-inch is the safe bet...
