Default Original or replaced harmonic balancer?

Took a few photos and a video of my harmonic balancer (uploaded to Youtube and linked here) I'm going to assume that it's the original?

Looks like a factory HB but can't tell if it's original. No wobble here,

If & when you do a replacement, go with an aftermarket unit like Powerbond or ATI

Just curious. Why would you need to pin the crank if you're not driving a blower?

There's no keyway on a LS crank. Slippage, even without running a blower can happen. If you're already into it for the hb spend the $25 and 15 minutes to go all the way.
