Try Google. I'm pretty sure I remember seeing that the later model engines were externally balanced, but only the flywheel had weight and the dampers were all neutral balance. I think LT1's are like that too.

I believe the extra weight on the flywheel was put there when they went to a one piece rear main seal. I read that a long time ago, so my memory is a little fuzzy! Better read up on it for yourself.
