DV definitely likes to toot his own horn. In my head it's the stereotypical educated British in him. 82 years has caught up with him and he is coasting to the finish line.
I really wish there were recordings of Harold Brookshire talking shop. That man designed the lobe, worked with the builder, studied the results, refined the lobe, and never beat his chest. He just kept at it.
Being a typical more is better male it's still hard to grasp not everything can benefit from the most aggressive parts (like camshaft lobes).
