Thanks for the info. After all the grease/crud was cleaned off the block, there is a small patch of light blue on the back of one of the original heads. Also, the valley pan had the same color on it. The odd part is that the valve covers and air cleaner were the same color. So, I suspected that someone painted either the entire engine, or at least the valve covers and air cleaner at some point in it's life.
Thanks for the reference to the other site too. cool site, and beautiful car that your friend has.
