I used stock rods from an old 455HO I rebuilt years ago (I put in forged units in that engine to replace these). They were just gathering dust on a shelf so I figured I might as well use them for something. They already had the ARP bolts installed. When the machinist inspected them he said whoever installed the bolts never bothered to resize the rods afterwards - a big no-no, since the rods were now bulging in the middle and were no longer round. As for pistons I went with new Sealed Power forged units from Summit.
