I have a fresh 289 that is on a stand in the garage. My old (factory) harmonic balancer took a crap and i need a new one. Should i go with some brand from summitt or just go OEM? Engine is built stock except for a mild Elgin Cam (.448 lift and .212 duration @.050).

Thanks

Your performance level does not warrant the fancy one. Get a stock one, spend the rest of the money on something important, like beer.

If it was rare, or your engine was custom balanced, I'd say get new rubber vulcanized in the one you have, but this costs as much as a new one.

I agree; stock or equivalent will be fine.

Just make sure it has the right number of bolts for the crank pulley.

professional products makes a nice one for like $60 that's drilled for 3 and 4 bolt pulleys, in case you want to swap to serpentine later

How do they account for the difference in pulley offset between the 3-bolt system, and the 4-bolt system?

both the 28 and 50 oz style they offer are manufactored to the early 3" diameter size...so it's compatible with the vintage rides.

If one wants to use it with the later style fox setup, they offer spacers to bolt to it between the spacer and pulley

Spacers. Good, because if you try to mix 69 3-bolt and 70 4-bolt you'll need them. Good to know.

I love the thing...it's got three sets of timing marks too, so no matter what you can always find the timing marks no matter which side your pointer is on.

before I discovered this balancer, I was freaking out about which one I could run

That's good to know that the Pro Products Balancers are set up for 3 or 4 bolt pulleys........................at $60 sounds like a great deal! The OEM type go for about $130.

Do not use an original one. You cannot trust 45 year old rubber.

They aren't 40 years old.

They are more like $110 for the Taiwan part (nice) and $60 for the Chinese (not so nice).

The rubber in originals can be replaced. Like new.

I don't think anyone was suggesting an original damper be used. I can't speak for others, but I was suggesting a new stock equivalent.
