I severely abused a lot of solid lifter Chevies to as much as 9500 RPM, but this only happened on a 307 I ran out of oil.

Not really my fault. I had just bought back a '63 Nova 4-speed car. He had pulled the "loaded" 327 for his '55 drag car, replaced it with a smoking 307, then sold it back to me very cheap.

....and he told me to keep an eye on the oil. I thought it would surely go 30 miles to the house. At 70 MPH, it locked up, and slid the tires. I found a rod through the block, and one through the pan! .......just like yours!
