Thanks for the kind words. If any of you are ever in San Antonio, look me up and we'll go for a ride. I'm at 9 lbs. of boost now. Once I get this engine is broken in I plan on running 15 lbs, so it should be fun.
Anyway, it looks like it was just the belt. I removed it and the sound went away.

Like I said, I've had such crappy luck that I can't help being paranoid. Better safe than sorry, though.
Thanks again,
Darian
PS What kind of Opel is getting the swap?
