Under acceleration, if you bang it into second when you wanted fourth, you
WILL over-rev your motor - the limiter has nothing to say about it.  Or
coming downhill, say...

I remember hitting 6200RPM in fourth in my Twin Cam Fiat and banging it into
fifth - missed and got third and learned that Fiat rod bolts are good  to
~7500 RPM!

That exhaust valve was banged into and broken off so it was in the way when
the piston was coming back up, so either the keepers let go, the spring
broke or the valve was floating...
