The difference is also there when considering that your engine is aluminum, the military engines of old are not.

Aluminum will warp if not cooled under controlled circumstances. You could completely destroy your engine if you were to just shut it down, because it wouldn't cool evenly.

Iron engines aren't like that. You can overheat an iron block, and run it that way for a good long time, and not really suffer any irreparable engine damage.
