Those in the three engines I have with Phoenix rods are all ARP 2000 as in Terry's photo, David. Earliest rods are, probably, from about 2007, latest Spring 2019.
Original ordinary Seven bolts are a very neat fit in drillings. What locates the rod halves with the waisted bolts? has anyone access to a hardness tester to establish what tensile strength originals are?
