How many, have nursed a knocking Rod home?

Worked construction with a guy who drove a '62 Chevy pickup and boy was it ugly. Straight 6 motor started knocking one day while we were driving to lunch. He was too cheap to have it fixed so he kept driving it. Ran with that knock for about 3 weeks. Then one day as we were leaving the jobsite he fired it up, made a few rotations and holed the block. Truck was silhouetted perfectly to see the eruption of oil and metal fragments. Swapped in an old 302 with a backhoe where it sat the next week.
