Is this normal?
Watch the video. The crank pulley is wobbling.

I've seen a lot of this and it seems to be normal as long as it's not causing any problems. I however would change it with an ATI or something that wouldn't wobble. I have an Innovators West balancer and it's rock steady.

I've seen worse, but it's not something to take lightly... when in doubt replace it

Make sure everything down there is tight if anyones removed the pulley to do maintainance work or something like that.

Wobbling crank pulleys tend to lead towards unhappiness.

The pulley will get replaced this year.

So far this week I spend about $400 on used tyres and new battery

Id throw an SLP 25% underdrive on it, just be sure to get a new GM bolt since they are torque to yield, and also make sure you have a big *** torque wrench since its like 240ft/lbs.

I could be blind but to me it just looks like the reflection causing the illusion of wobble. Best bet is to at least check that the bolt is nice and tight.

You need to look straight down on it. Not at an angle. Make sure the bolt is tight.

What's the problem here?
Is the crankshaft pulley going out.

Watch this video.

Mine did the same thing on my LS2. I took it to the dealer and they replaced it. A couple weeks later, it started doing it again. I had the balancer bolt replaced with an ARP. Turns out, looking at the bolt the shop took out, the dealer installed the new balancer with the old bolt with an impact gun. The threads were rolled on the end of the bolt and I highly doubt it was torqued to spec. Not to mention they are TTY bolts, and are not to be reused.

And to think, the tech that did all this is a multiple "Golden Wrench" winner. So now, I'm trying to figure out what kind of pulley I'm going to put on it. I'm thinking of going 10% underdrive, not much more because it's mostly street. I track it on occasion (4-5 times/year).

A lot of us have had that happen, including me. My pulley bolt came actually loose too. I would replace the pulley and bolt. Don't re-use the stock bolt.
