Ahhhhhhhh crap. Rookie mistake. Buttoning up my 5.9 Magnum short block. .030 over, new pistons installed on rods and in the block awaiting plastiguage check on rod tolerances with new ARP standard rod bolts. I did not resize rods. What now? Reuse old bolts or carry on? Engine had 100k on it. This is a street motor under 400hp. No track and no crazy revs.
Did you fit the new ARP bolts in the rods yet? If not, then keep the old ones in there; your use is not severe. If the ARP bolts are in already, then that is the potential issue if they had to be pushed or pulled in hard.
To be honest, I have never replaced a rod bolt in anything, including my Opel and Mitsubishi rally car engines that have been hammered on over and over. I suspect most of the failures come from come from poor install work (not torqured so too loose or overtightened and thus stretched) and from pushing the stock bolts beyond what they were designed for.
