Not really balanced - LS2
As powerful and strong as she is the LS2 has an unbalanced sound (at least in mine). Does anyone else feel that the C6 should sound more evenly balanced? I don't really want a louded ehaust just a less lumpy - a little more F1. Anyone else feel the same?

Feels good to me. Much less refined than other cars, but it's supposed to be a big, brutal V8. That's the point!

Hmmm... I read all the comments... My baby sounds and feels very refined to me. When she's idling, when I wind her up, she sounds/feels VERY balanced. American V8? Yea, but to me, not like small blocks of the past, more like thoroughbred European cars of today....
Just my 2 cents.

What do you mean by unbalanced and lumpy. We may have a communication problem here. Lumpy typically means an uneven idle mostly associated with V8's that have an aggressive cam, or older carbutated models that need a carb adjustment.
The F1 sound you're looking for can only be had with smaller displacement engines, with 4 valves and a redline above 7000 rpm's. maybe you could expand a little on what you mean.

The feeling is not like a heavy cam - she feels like 2 cylinders are stronger than the rest of the 8. Perhaps mine is unusual... It is definately not a weak engine. It is just that there seems to be a surge in the 8 piston firing cycle. No one else feels this? I am a little sensitive to this kind of feeling since I have a long history of motorcyles.

Even if the LS2 could rev to 10 grand it wouldn't sound remotely F1.

I guess GM shouldn't ship them overseas on their side anymore...sure you can fit more of them in a container, but with this whole unbalanced engine thing, it hardly seems worth it.

On a tangential note, Nascar V8's (old school OHV) often run higher piston speeds than F1 high RPM engines with a very short stroke 
Also, HP/Ib-motor, its really hard to beat the LS series V8 which spells performance if not "refinement".

Your explaination completly makes sence. Thanks for the effort!
