Is there a way to identify connecting rods without weighing them? The weight might vary because of missing or damaged babbit. Ford may have used several suppliers for the rods but were any stamped ith a part number or identifier of some kind?
Thanks

The older rods look wider through the web of the rod. They are fairly easy to tell from the later lighter rods. Most of the suppliers won’t accept the older rods for exchange because of the older design and weight. They won’t rebabitt them. Or they use to not do it.

Yes the rods were forged with makers mark, but there are too many to list here. While the marks are shown in the Service Bulletin Essentials, they are not cross referenced to which type rods they go to, except maybe by using the date when Ford posted the charts, but that might not be helpful, as the same company could have made different weight rods.
There are 3 types of rods, heavy, medium and lite. Medium and lite are really close. Looking at where the shank meets the part where the babbitt is poured; heavy is about 1" across, medium is about 7/8" and lite is about 5/8".
Craig, you may be posted the wrong link?
