Also you have to consider that after you plumb and cool the turbos (especially for a 600hp application), you will probably negate any potential weight distribution improvements. LSx's are so cheap, and so easy to build, that I really feel that they are a no-brainier. It's not like the LSx is an iron big block or something, as long as you set the car up right you can get a very good weight bias with it.

There are a lot of things that affect the sound of the exhaust. I usually like the sound of an engine with a really aggressive cam and very little exhaust, that tends to give it that guttural rumble.

Nate:
I forgot a couple things.

"There are a lot of things that affect the sound of the exhaust. I usually like the sound of an engine with a really aggressive cam and very little exhaust, that tends to give it that guttural rumble."

I agree with you. I too like the guttural rumble, but what I was wanting to understand is the CAUSE of the Rumble.

It can't be a function of merely having 8 cylinders. I've heard v12's that have a high pitched scream rather than a low rumble. Also the Harley V-Twin has a great low Rumble with only two cylinders.

It must be a function of the size of the Cylinder and the Shape rather than the number.

Is this plausible?
==================================
ALSO:

As I mentioned in the post following this one,in the "Trans Am" road races of the 60's, the Camaro 302 Z/28 was not a torque monster, it made it's power up high.
(Not meant to be confrontational, just purely for the sake of discussion)
By your reasoning, wouldn't that make the V6 Turbo a good Road Racing Engine?

Thanks,
