I just pulled these out of my 1972 455 HO during the rebuild this month. The engine also had L2394N high compression pistons (for sale separately) and I wanted to go back to a stock configuration.
The car ran fine with these rods. The engine had 5,000 miles on it. They have had the casting seams polished out and have been resized but I would have them rechecked prior to reusing them.
$100 or best offer, plus shipping.
Here are a bunch of photos of the set:
