You would be one of 2 or 3 to ever do that to my knowledge.

If all you want is a power number then yes, I'd go with a huge cam like that. It's not going to be fast, but it will probably make the power you're looking for.

I assume you plan to go swap the heads and intake right?

Do you have any reason for trying to do all this with a 5.3L? It would be much cheaper to swap to an ls1/lq4/lq9 or bigger.
