How do you know this person was qualified to give advice?
To see how the factors of flow and displacement affect the cam spec required, let’s start with the seemingly disconnected issue of fuel octane.
Fuel octane influences the compression ratio that can be used and an engine’s CR must, for best results, be tied to cam duration.
For most engines, detonation occurs at low RPM because of the greater length of time the end gases are exposed to the advancing flame front.
When a long cam is used, the compression pressures at low RPM are reduced, thus not only allowing—but requiring—a higher CR to be used.
Obviously the piston will be well up the bore if the valve closes late as per a long- duration cam.
