Thanks for your input. It's good to know that you have 4.7's. I forgot about losing momentum until you brought it up. I lose momentum going from 1st to 2nd with my stock transfer case, I couldn't imagine what a 4.7 would do. When I hold it at 5K is only for around 5 minutes and my dad and I built it to rev higher with stiffer valve springs and a full rebuild, but it is hard on all the components.
