3:55 gears is one of the best upgrades that I have done. Like said above, whether this upgrade is for you or not depends on where you live, and your plans for the truck.
If you live in a hilly or mountainous region, and you tend to drive on short trips or just locally, with the 216 you may want to stick with the stock 4:11's. But if your plans call for long trips to meet other fellow Stovebolters, you will love the 3:55's
Seeing that you live in Texas, hills may not be your issue. On flat Texas ground you could get that 216 up to a speed faster than your brakes can stop. Make sure that you take the time to make upgrades to items like suspension and brakes and ensure other items like steering are operating in great shape to make your truck a good driver.
I have done three of these upgrades, if you decide to proceed or have any questions, just let me know.
