no question - I agree with JW that the guy is a "genius".

No question, the article was great, and I agree also with JW's comments that we would have liked even more detail and info.

To be "picky", I would note I am unclear, however, how he got the idea that Packard rod bearings had "bronze" in them. Yes, the original "insert" type rod bearings introduced for 1935 production had a "BRONZE" color. They were a joint effort by Federal Mogul (which is where Packard got em) and were a "sintered COPPER lead" not bronze). I dont know enough about metalurgy to suggest well a "BRONZE" insert will behave on a "hardened" Packard crank-pin compared to copper.

There was some fooling around with a "cad.silver" bearing surface ( a set was found once in a Packard I helped pull apart;) probably the result of a field overhaul during or after World War II. At some point in time, Federal Mogul was selling to Packard the "cad silver" insert, as a substitute for copper, which was a "vital defense metal".
