Default Harmonic Balancer Recommendation

So another member suggested I check the balancer on my 1985 L98 as part of buttoning up another job. I know I don't need anything aftermarket for a stock engine. I searched the forums but did not find anything recent. These are what I found for a non-modified engine. Which of these would you recommend or is there another better solution out there?

I'd go with the Summit unit (made by Pro Race). They make good dampers. I have their mid-level "Pro Sport" damper on my 383. It was recommended by one of our forum's "visible" builders.

Not sure how I feel about AC Delco since they sell any import part rebadged as theirs...making it kind of a crap-shoot. Dorman can be cheap, though well-known and not the worst. Dorman isn't a bad if you NEED to buy from a "budget" line.

I installed a a Dorman on the stock engine I rebuilt for my 84. Worked just fine and still doing good after 5000 miles.

Ive had very good luck with powerbond dampers. You can get them from o'riley or summit.

they seem to be well made with properly indexed timing marks.

I have the summit unit on my car, seems to work great.
one tip tho, dont wipe it down with brake cleaner before installing or it will remove the clear coating they put on it.
​​​​​​​hard to see the lines once it gets a nice rusted finish...
