I learned an interesting lesion when changing the engine mounts on my '74 F250.

Turns out it's a really good idea to chock the wheels. As I lifted the engine, the column shift linkage had just enough travel to pop it out of park. It rolled just enough to cause brown shorts before the engine dropped and the parking pawl caught and brought it to a stop.
