Parts, materials and lubricants have certainly advanced by leaps and bounds, since then. Could effect the physics of it all in a major way. I will admit, I was a little pissed that the automotive journalist of 30 years, who authored the piece, seemed to dismiss Jenkins, as well as Yunick and Lingenfelter, as being wrong. Unfortunately they can`t comment. I think its safe to say, that if you are going to disparage Bill Jenkins about race engine physics, you better pack a lunch. Just my humble opinion. Not sure what oil he used, although probably heavy, Factory castings, forgings for blocks, heads, cranks, until the aftermarket caught up.
