I'm thinking more and more that the stuff in the radiator is DexCool Sludge. Look at the attached link if you want to see some scary photos.

I also figured out why the stuff wasn't disappearing when I was flushing the radiator; I was using a cold water flush when the engine was cold.

Instead, I warmed up the engine and opened the petcock on the radiator (what a pain to get to the petcock). The water from the radiator drained into a bucket and I could see the sludge in the bucket. I'll do that a couple of times and the sludge should be gone.
