How do you find where a blown Flathead tips over on the dyno?

The engine was still safe and still making power all the way up, so the crew decided to run it up to six thousand and see where it tips over. With a blower it is expected to carry a little past the peak, but not much. Asked what RPM he was running, the operator answers 300 revs per second, and the pull stays at 300.
