Which should I balance my rotating assembly with?
Im in the middle of an M6 swap as well as a 383 stroker build up. Now when I balance the rotating assembly do I balance it with the flexplate from the auto, or the flywheel from the M6?

Niether,
Balance the internals with themselves. The bobweight is the only thing that matters, unless it's a 400 build up then it's an externally balanced crank. Which it's not.
Use the flexplate or flywheel for whatever you are going to run, both of them should be balanced by themselves so you don't need to include that with the engine.

ll this internally/externally balancing stuff is tricky.

Actually, you could go either way with this.
You could:
A. Have the entire assembly with the stock flywheel (which is counter weighted on a stock LT1 BTW), and the rest of the rotating assembly all together. This would allow you to use any flywheel made for an LT1.
or
B. Do what Brett said and have them both neautral ballanced. Just keep in mind, that if you ever had to replace the flywheel at a later date, it would have to be neautral balanced also before installing it.
Stock LT1's do have a counter weighted flywheel and are considered internal/external balanced. The front dampner is neautral balanced, but the flywheel is not. At least that is what Callies told me when I purchased my crank.

If you're going to keep the stock setup then after you resurface the flywheel give it to the machine shop so they have it while they balance the rotating assembly. If you're switching to a completely internal balance setup then you need to have the flywheel neutral balanced as well.
IMHO having the entire thing internally balanced is better but it could be more expensive.
