Do they make a stretch gauge fixture for torquing ARP studs?

I remember an article in Hotrod years ago about them losing a rod in a SBC after the bolts came loose. They found the nuts in the pan. When they checked the stretch after torquing to factory specs they found the bolts weren't close to tight. It ran for a while too before it went boom.

Maybe that's what happened here. Partially/improperly torqued fastener held on for a while and then fell apart.
