Today, dollar for dollar, is the 318 faster than the 340 ???

These are 3 pages of Bettes’ book “Engine Airflow”, a must read book if anyone is interested in understanding the internal combustion engine at a higher level. The one quote I was referring to is the one where Bettes points out that horsepower is proportional to bore size. Also notice he slays the sacred cow that torque is the be all, end all, and that it’s horsepower that does the work, not torque. If you don’t agree with that, you could take it up with Harold, but he has passed. His written words still stand as a testimony to his thinking on the topic.

EDIT: I have removed out of order. The middle shot should be the last one and the last one should be in the middle.
