WTF hapened to my harmonic balancer?
WTF hapened to my harmonic balancer? What happened here it looks like it is starting to separate from the hub there? First question: Does this mean i have to buy a new one?
Second question: It has a lot of holes drilled in it, so if i just simply pushed it back together would my rotating assembly be out of balance?
And last: Does that big bolt in the center of the hub have to come out to pull the whole thing off from the crank? Any one can help me out here i would appreciate it.

yes the middle bolt has to come out to pull the entire hub out. If your just wanting to replace the pulley then no. Just remove the 3 bolts and pull it off. Yes your stuff looks messed up. You only need the pulley. It isnt a "traditional" style balancer, so you wont have issues. Some did get "fine" tuned from the factory to get rid of any extra vibrations but the LT1 is balanced a different way
The pulley can only go on one way. If you put it on wrong the bolt holes wont line up. So you cant put it on wrong. FYI

First question i dont know.
Second question--- The balancer will only fit on the hub one way, so if you aren't removing the hub, it wont matter. The LT1 is internally balanced, so it shouldn't matter. I believe the Hub/balancer are neutral balanced.
Las question--- Yes, it would have to come off it you plan to pull the crank hub and balancer together.
Thanks Guys So i can just buy the pulley and leave the rest on there? And your saying that my car has a different style pulley than most? Does that mean its a dealer item? Wonder why my car would have been balanced more precisely than most of the others? Or was it just so far out of balance that they had to balance both sides?
Ya that looks like a potential catastrophic fail.
Go to the Junk Yard and just find an LT1 Car with a Balancer on it and get that.
The LT1's are different from the SBC's..that is all that those guys were saying.

All LT1's were balanced the same from the factory, internally balanced at the front, externally at the rear. The pulley is NOT a balancer, it is a harmonic damper. You can simply swap out any stock LT1 pulley and just bolt it up and go.
Oh okay. The junk yards around here get picked pretty damn clean i have only ever seen one lt1 car at any of the u pull it yards, and it looked like it hit a pole at about 145mph. It was red that's about all the more i could gather from it. There was nothing left of it.

10 Camaros You Should Never Buy
I am not sure to b honest with you. I just bought a replacement at the parts store. I called all the junk yards in the area, and as usual the diden't have so much as a valve stem to fit my car.
the balance is supposed to have 3 smaller bolts around it and then the one bolt in the middle.
Here's a link on how to take it off with good pictures:
