After ripping our Z06 home last night I was reminded that it once had a nagging engine knock. I mostly remembered this because I was the one who bought the thing and would likely never hear the end of it should it spontaneously self destruct.
After an extensive fact finding mission by our resident engineering staff, the problem was eventually found and fixed. Since then, it's been flawless. Haven't heard a ping since. Okay, maybe a random one here or there, but our M3 sedan used to do that on occasion too. When you wind up a street engine to such a degree, it's bound to happen once in awhile.
That said, the LS6 in our Corvette is an amazing piece of work. It not only sounds great through the titanium exhaust, it makes great noises from inside too. There's just enough valvetrain noise to remind you there's a serious V8 sitting not too far from your feet. It's a sound that's rarely heard in modern cars these days, so much so that passengers sometimes think something is wrong. Nope, it's just fine I tell them. In fact, it's just about perfect.
