Wish you were closer, I could fix it for less then there tear down money. ANY gm dealership should recongnize that this is whats wrong with your truck. pm me if you need anything if they tell you its anything other then new cam and lifters i bet they are guessing...

A 5.3 liter with worn cam lobes? Can you post a picture of a worn Gen III roller cam?
