I agree,,,,very rare I feel .
Yes,,,I have seen them taken beyond their limits,,,,,and fail,,,,but it was after repeated abuse .
I had a friend that had a factory 440 crank give up the ghost,,,,but it was after 2700 passes in his Cuda !
That car would carry the front wheels close to 4 feet off the ground !
Even the people that didn’t like Mopar would line up at the railings to watch the show he put on .
He left on the two step about 3800 if I remember correctly,,,,,man,,,,what a show .
When that engine finally let go,,,,the crank was in 3 pieces,,,,and the block had all the main webs broke .
It was all contained in the pan mostly,,,it let go on line at launch,,,,so that was a blessing .
We’re still not sure if the block failed first or the crank ?
