I'm a little surprised that there isn't any noticeable debris in the oil if it really is knocking that loud. I have only grenaded one engine in my life (the 2.8 in my '85 Camaro), and when I drained the oil it looked like paint from an 80's pro street car. After lowering the pan we discovered that the #4 rod bearing had been completely torn up and there was no part of it left on the rod / crank (keep in mind, the car was still running and drivable at this point, but there was a very noticeable lack of power (no v6 jokes). I had been driving it with the rod knock for a few months and was shocked that it held together.

I don't have much LS1 experience, but if it really is knocking that loud, I would definitely assume it's the glorious sound of a rod bouncing on the crank.
