Clutch or tranny vibration?? Suddenly started doing it..
Ok so I was in first and gas'd it a good bit from 2k to about 5k and let off. Right after that I started getting a bad vibration in all gears from 1600-2400 rpms...I'm thinkin pilot bearing or clutch somehow got unaligned...what do yall think?

Take the dust cover off the trans and see if there are any obvious signs. Just to clarify, can you be at a standstill, in neutral, engage and disengage the clutch and there be a vibration when clutch is engaged?

Okay so I just cranked her up and the clutch was chattering like hell while I was holding the pedal down (disengaged) I turned it off right away because it sounded like it was about to blow lol. Time to rip the tranny back out.

I don't think it would be a good idea to reuse that flywheel. It's very possible the bolt holes as well as the centering flange hole have been elongated and may not sit true on the crank causing more vibration. You should also inspect/replace the pilot bushing/bearing and inspect the input shaft on the trans to make sure it too was not marred/damaged.
At the very least I'd have a machine shop look at the flywheel to see if it's still good.
Either get the bolts from GM or buy these:

Keep them then, unless there are signs of damage. You will also want to make sure the clutch disk is not bent. There's no reason for the ARP bolts to back out. IIRC the torque spec for the flywheel bolts are 74ft lbs. You may want to look it up to be sure, or call ARP and ask them what they recommend the bolts be torqued since they may have a different rating than stock GM bolts.

Honestly the guy that owned it before me didn't know much about cars and the only thing he did was change the clutch/flywheel. I think all of the parts are still good. Because I woke up one morning, started it and it started happening. I immediately shut it if and haven't run it since. It was vibrating a little the night before it got really bad. But that's it.
