Yes, Brent does invoke some interesting conversations.

And while I do agree that technology today, as far as manufacturing is much better, it still has two limitations. The first is the operator of said machinery and tools, have you noticed the machinery is more complex and requires less operator input? But it still relies on an operator. (less crank handles and more switches and knobs)
The other factor are the materials that the parts are made from, at best, 90 year old metallurgy and quality. FWIW, it is pretty good, but a limitation.

I was having dinner with a very wise engineer from Cosworth some years ago and we were discussing materials and coatings. This was the time of ceramic coating everything and moly spray coatings, before cryogenic treatments. "If you have to rely on some sort of surface treatment to make the assembly live, you have the incorrect material in the parts". Since we cannot change the materials we have to make changes to design and accompanying parts, such as pistons, rings and bearings. A change to the oiling system makes a world of difference in the materials and construction.

The process of "break-in" today is a much different process than 80 years ago.

Best, John
