One of the problems I noted with my "other" brand(BBF)hot rod truck, was that the stock pickup frame is subjected to some tremendous tortional forces. Especially if you are planning on tubbing and/or running slicks.
This is most obvious directly behind the rear cab mounts and I had some pictures that showed the bed to cab alignment went from 1" at the bottom to a full 3" at the top during launch. It became obvious that hooking up was going to take a toll on my driver's side frame. It was a factor that I had overlooked that should have been addressed early in my build.
Regardless of your rear suspension choice, you should be aware that big rwhp comes at a price and that to get a pickup competative, you'd be wise to make reinforcements before the fact! Just something else to kick around!!!
