Rich, you made this comment earlier:
About the cam, I don't know about Voodoo cams as opposed to other company's, but I can speak to the cam specs. Lunati says that's a great "4x4 and marine" cam, but lists the power range on that cam from 1400 to 5800 rpm. And the lobe separation is 112*. That sounds like a winder, not a lugger, to me. You are putting this engine in a 5000 pound truck. You want torque, not horsepower. A torquer cam should have a lobe separation much tighter, like 108*, and shorter valve durations. A 262/268 cam is going to have a much later intake valve closure and much earlier exhaust valve opening than you want for torque. That indicates that cam is designed for high-rpm horsepower, where those numbers will help the engine breathe and give higher horsepower. Great if you are circle racing. But for street use, you spend almost all your time in the bottom half of the rpm range.
Look for a cam with 108 LSA, shorter duration, and a lower recommended rpm range if you want better street performance. Don't fall for an old-tech grind, though. Subtract the duration at .050 from the end-to-end duration. You want a difference of 40-50 degrees. Larger difference are characteristic of older grinds, while the newer computer-designed grinds get the valves off the seats much quicker, which makes it easier to maximize performance parameters. On that score alone, you can see that the Lunati cam is a modern grind.
I thought it was the other way, that 108 was a high horsepower LSA vs 112 being for torque. I know there is more to it than that, but just wondering.
