I think, on rare occasions, I have heard this same sound. It has concerned me also as I am running on the ragged edge of detonation with 10.3:1 pistons (in a 3.2) and 93 octane fuel.
I have probably heard it twice (once on the track at Daytona during the Rennsport lapping for the posers - how cool). I'm very familiar with the sound of pinging, though, and this doesn't sound like that, but it is a disconcerting sound.
