Ok, I gotta know.....who has ever tossed a V8 TB and busted a piston??

 I ask because I've been inside a bunch of V8's with tossed TB's and not a 
one has had more than a couple of shiny marks on the pistons from the 
impact..... That includes one V8 that had wrapped the belt around a timing gear twice 
and had bent two valves into an "S" shape. I'm guessing that engine was pushing 
around 6k when the belt went.

 Those intake valves are tiny and thats one very robust piston.
