I've got my own autographed copy. Just making reference to the fact his opinion might have changed given what's available today.

Re: i know there are some great engine builders here
 

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.

Trust me Jenkins was my hero along with Smokey. I met both of them and are the few people I ever wanted an autograph of and got.
It's not so much the physics changing as the materials and availability of it changing. If you look at what they did they made everything themselves with the want to. They had only factory parts to work with and made their magic from there. The equipment you can buy today wasn't even available. Could you imagine the level they could or would have gone to with computers and CNC equipment?

I absolutely agree! Had to develop & make things we just order now.

If only Bob Glidden had written a racing engine book.

Re: i know there are some great engine builders here
 

I was trying to explain the advancements, to a coworker, a couple days ago. We don't live an hour away from Ohio Crankshaft and I was explaining that, we could drive over and buy 1000 Horsepower plus and be home running it in a few hours. He raced in the 1970's and had no idea of the aftermarket parts available today.
