Great writeup on Dynamic Compression

Iron heads correct? I'm thinking one has to have a number of factors right - good cooling as you have pointed out, mixture not too lean, right plugs... I'm sure you can add to the list.
The article seems to suggest there's a middle ground with more cam than typical without lower RPM losses.


I read it and I agree. There is a middle ground, and right now, I'm shifted past center on the middle ground. The next engine I'm going push even farther from the middle.

Of course, I could fail hard. But I'll never know if I don't do it. And I know Crower was doing it in the early 1980's.
