How many times can rod and main bolts be torqued?

Just as an example.. A friend ran NHRA Stock Eliminator. He was on the 2-step at 6800, shifted at 7200, and trapped at 8K. The engine had stock pistons, stock rods. Those rod bolted have tens of cycles on them between teardowns for inspection, occasional piston replacements, and record tear downs.
If you don't over torque, you can retorque them many, many times. But - the one time you go too far, they're junk.


Does he really have "Stock pistons and Stock Rods"....or does he have Nhra approved replacement pistons and rods...which are forged pistons and rods...?
