The one I had blow was an 11 liter Dodge diesel. It was a steel sleeved iron block design. One of the sleeves split, I'm not sure what else was lunched at the same time.

It left a very impressive steam screen. The problem with that was the tailpipe exited under the Front bumper, my vision was obscured.

OUCH!
Good smokescreening, but in the wrong place..
Blew up a chevy V-6 once, but I don't remember HOW we did it.
What I DO remember was: We were doing a 65 mph(at least) sprint down the highway and then dropped back the speed for backroads when there was a ghastly lurching, blue-grey smoking from everywhere at once, and then a sudden stop.
It was an education.
We walked the remaining 4 miles home in record time to get a buddy who had a towtruck..
