Re: What oil do you use in your V8 Packard?

For those that have access to the February 2010 Studebaker Drivers Club magazine Turning Wheels, there is an interesting picture and comment in the Co-Operator section about lack of enough ZDDP in the oil used in a brand new Ford 429/460 rebuild. The cam and flat bottom lifter shown have some severe damage and claim is bearings and journals also show damage. This was after only 20 minutes of "proper run-in time" and will require a complete rebuild again due to "metal fouling the oiling system".

I don't pretend to be very knowledgeable in either engine wear or oil but does this seem realistic? Apparently the Valvoline VR1 racing oil (and others) is said to have the correct amount of the stuff but the article doesn't mention what that is to be on the lookout for.
