and here's the engine. I glad I pulled it out when I did. Over the years I've replaced 4 of the 6 freeze plugs in the block. The two I couldn't reach were blocked by the K-frame and impossibe to reach with the engine in the car. When I pulled the engine out and started replacing the oil pan, valve cover and other assorted gaskets, I decided to replace all the freeze plugs as well. The two I never got to actually had holes in them about 1/16 inch wide. The only thing holding the water in the block was the accumulated rust and scale on the inside of the water jacket. Let that be a lesson to everyone: Change your antifreeze often!
