Is your rear the 10.2 or the 10.5? The 10.2 is ok, but if it is the 10.5, those rear ends can hold a lot of hp. I also agree that you could get some more hp and satisfaction out of a motor that you had built to your own specs if you havent already bought your motor. If this is something you are considering, I would get an idea of the parts you want to run, and call up a company called Revolutionary Performance to get your motor built. They are really nice people, and from what I have seen and heard, they do great work for a fair price.
