Did you try belt dressing?

I did replace belts. Car has 90k miles. Just spraying the pullies.

sounds to me like a tensioner is going out and might be making noise if you've already replaced the belts.

You may need to replace multiple pullies. I just did on mine and a lot of the noise has gone away. Fred Bean Pontiac is great to deal with. Great price and service. Belt dressing did not really do anything for me before I replaced the pullies. Also, I am 99% sure that the pulley bearings are sealed and that there is no way to clean and repack them. I think the belt tensioner pulley bolt is 15mm as is the lower A/C idler pulley bolt. The upper A/C idler bolt is a Size 50 Torx bolt. If you are skinny enough, you can slide under there and do it. If you are on the larger side, you may need to raise the front up. Make sure your belts are aligned properly when you are finishing up.

Are you using cheap belts?
Gatorback belts will fix that squeak

Which belt is it?

I have never heard my main belt squeak... If it is the main belt then it is for sure the tensioner if you have not been in there messing with any of your pulley's

I have had my AC belt squeak and changing the belt fixed it.

There should be no need for WD40 or Belt Dressing on a stock LS1. Thats what the tensioner if for.

+1 on the gatorback belts.
Even if your pullies are bad it will quiet them down aswell. As far as belt dressing, som folks swear by it, but I'll never use it. It doesn't solve any problems....
Its like having diarrhea and putting a cork in your butt...
Its solves the symptoms but not the problem

+2 on the Gatorback belts.

Also, if you spray them with WD (or use belt dressing) and they quiet down instantly for a while, that tells youthat the noise is the belt, not the pullies/idlers/tensioner.
