Well, mine is pretty rough at times, but I think the cam might have something to do with it.

Mine idles pretty smooth, as far as vibration. The idle speed does tend to vary since the addition of the ST3500 a while back.
Heck, I had a '68 Chevelle that would shake you up,and had a classic loping idle,solid lifter cam that would intimidate the devil, but wouldn't hold a candle performance-wise to this LS1 (I rebuilt a 327 HP in '78 for that Chevelle).
Plus I don't have to adjust the lifters / rockers every week.

Mine idles smooth, I have 2700 miles. But it seems to idle a bit low, about 500 in gear, according to the factory tach.

1999 30th with 14k miles is pretty smooth but it is a M-6. 98Z with 70k miles is a littl bit rougher, but not to bad at all.
