from description..
motor broke at the camshaft. The top half of the block was ejected from the truck. Driver was unhurt.

I guess due to the forces involved both halves of the engine were flung violently in opposite directions.

This event is a tractor-pull, in which you pull a sled that's progressively digging itself further into the dirt the farther you go. So these engines are made to have insanely high amounts of torque, meaning that when something fails, they've got more than enough power to just rip themselves to pieces.

Or if you prefer, that dang ol motor got so much twist it done twisted itself right on outta there.

All the stars for the Boomhauer translation
