IMO, there was no need for rocker shaft design in the Packard V-8 since the RPM was not that high.



When the Studebaker and Packard V8s were being designed, the best practice they had to copy were the first-generation Kettering Cadillac and Oldsmobile V8s, and copy they did. The Pontiac and Chevrolet stud-and-ball innovation didn't debut til long after the S-P designs were locked in.



True, but I'm just sayin' that the rocker shaft design was an overkill.

Some old crud which may come loose in the rocker shafts is not the same thing as ditto in the main oil feeds.



Craig, you're going to have to help me on this one. Why is crud in the rockers coming loose and circulating less damaging than crud in the main oil feeds coming loose and circulating? To me, crud in the oil is crud in the oil.

My point is simply that old crud coming loose in the rocker shafts is NOT going to the bearings directly and will (hopefully) not be as destructive as old crud going directly to the bearings. With the bypass oil filter, that is really hopeful. A minor, minor difference, I'll grant.
