Glenn's advice to grab a takeout package for now, and then have more time to build your existing engine the way you want it is a good idea if you need to have the truck for your daily driver, but regardless calling the TechLine at Edelbrock to get their advice on the cam selection and compression ratio is solid. With your description of how you plan to use the truck, and what you'd like to have from it they can give you good advice on the cam. You'll need to tell them what rear gears you plan to run, the diameter of the tires and your tranny gearing to pick the right "sweet spot" for cruise while giving good power.
When I was working with my ProFlo XT I spent hours on the phone with their guys, and we even had the ECM on line in shared mode so they could see what was happening - in fact that identified a problem when they were watching the system voltage during crank, and pointed out a wiring problem I had. Good guys, and like Glenn they sent me a "demo" fuel pressure regulator when we determined mine had ruptured.
