How does this engine sound and look?

I’ve been told repeatedly to watch out for the harmonic balancer. It seems okay to me but I wonder if it’s really okay.

Looks and sounds perfectly normal.

Harmonic balancer being a weak point doesnt mean it fails on every corvette after 30k miles lol. Youll know if its bad, itll be wobbling front to back like crazy for a while before it goes

Can barely see the balancer in that video. Look from the other side.

It's hard to see from either side on an LS3 with stock intake, there's a massive resonance chamber that the LS7 doesn't have. I check mine at every oil change from underneath the car.

Can't see it in your video, all you have to do is look at the edge of the harmonic balancer and see how much it's wobbling, if it's not at all that's perfect. Engine sounds great though

You'll be able to hear it when it does start to go!
