Didn't I read somewhere about a natually occuring harmonic vibration in the flat 6 engine design that happens at around 3,000 rpm?

I've always had it in the back of my head to drive either just below or just above the 3,000 rpm threshold - there again at my advanced years, I could be talking out of the back of my head too......
But the everyday sweet spot must be in the 3,500 to 4,500 rpm pulling through the gears - very addictive!
