Finally put the water pump in. After reading the data from Brads links above, I decided to put the put the 440 Source pump on the shelf. I was more concerned with the low RPM flow. I picked up a NAPA pump, which I think is only marginally better.
I also installed a new fan shroud. Mine was missing. If it stays dry, I may take it for a spin around the block.
Now I'm waiting for the new dash pad. Yippee.
