Marc,
I am not sure what dog picture you saw, but I am on 3 and 4. I usually take them with me in the Panel, weather permitting. When I leave them,they both sit there and look like they just drove up. I was coming out of a place and heard a kid telling his Mother, that dog didn't drive that truck did he?
As far as the engine goes, don't tap too hard with the block of wood, you don't want to break the piston lands and grooves. Have you taken the pan off and loosend the bearing caps? I have not freed up an engine myself, but I am thinking if the pistons move at all, it is the crank that is most likely frozen. I have heard on here before that it may take a couple weeks for solvent to soak down and free up the rings.
Here is a Panel on E-Bay that may be of interest and it is in your part of the world. You may be finding out that after you get a Stovebolt, they begin to attract others.
