Crap, in the process of flushing the cooling system my water pump started leaking. I guess it's time to replace that too. The pulleys were wobbling and noisy, so that was probably why. The pump is a little different from a small block pump, but it looks like 4 bolts hold it in. Hopefully they'll come out OK. While I have the fan and pulley off, I might take the opportunity to replace it with an electric fan to make it quieter and free up some HP and fuel economy.
