How the hell do I get the crank pulley hub off? :(
Wow, I thought it was going to slide out.. had to buy a puller and the bolts it came with were too short. After running around all day I finally founds some bolts that fit. I got the pulley off; but the little hub behind it wont come off. How do I remove it?
If you all need pics let me know, I can take some.

There's a special tool:
I think people do get them off without that tool, but it's a PITA.
A steering wheel puller works if it's out of the car.

Remove the center hub bolt going into the crankshaft.
If you are using a conventional balancer (crows foot) puller, you must insert something into the hole where the center bolt was, so the center shaft of the puller will have something to push against. It needs to be something that is very hard and will not bend (some people have used socket extensions - be careful, though). It also must stick out far enough for the puller to work. You don't want to harm the threads of the crankshaft.
The specific puller for the LT1 uses a hardened threaded adapter that screws into the crank.
After you get that set up, it is just like pulling any normal balancer.
