wobbling harmonic balancer

The engine is all original and has about 127k miles on it. Still runs great, but I happened to notice the harmonic balancer wobbles quite a bit. The crank pulley rotates completely smooth and I don't hear any scary sounds. Just wondering what I need to do about it. I'd like to put on a power-adder in the next couple years but I need to address this first. Thanks for your input.

If the HB is wobbling the car won't last a couple of years, You are talking days with serious engine failure especially if you start to spin the engine. End of story.
 
The stock balancers come apart rather frequently. The rubber ring that bonds the innner and outer hub fails and the the outer hub balancer spins free. Replace it now before it comes apart and causes problems.

Follow the link and take your choice. Remember that there are two different balance weights, 28 Oz & 50 Oz, depending on when your engine was made.
