Thanks, Turbo
I'd like to see that data, if you can find it.
Just today, I was at the Nostalgic drags in Beaver Springs, Pa. I got to chatting with a fellow driving a nice W-30 Oldsmobile. He was telling me he drives his Olds on the street and races it too. Recently, he replaced a fairly low-mileage cam and lifters because he found two lobes were significantly worn.
He also has heard accounts of cam wear and the cause was because of 'some additive' no longer being put in modern oils. I assume that additive is what you spoke of.....zinc. If that's true, folks with older flat-tappet cams like mine, will need an additive with zinc in it.
I await your confirmation with the data if you can locate it.
Thanks again.
