429 timing help!

I solved one problem and found another. Long story short, I checked my timing and couldn't see the timing mark? Where could it be? Last time I set my timing it was between 12-14 degrees advanced, that was about 400 miles ago. I moved the dist clockwise and I could see the timing mark come into view. As I got closer to the marks the idle got worse and worse, shaking the engine! So I backed it off and set it by ear. It surged when I cranked it over so I retarded it a little more. Still runs rough but what the heck is going on, it is as if the balancer rotated on the crank clockwise about 30 degrees. What am I looking at here?

429, D3VE-A2A heads. Edelbrock power pack cam/manifold/carb combo. Mallory distributer (mechanical advance only)

Re: 429 timing help!

Good chance you are correct in saying the dampener moved. The outer ring on those is mounted on rubber and when they get old it's not unheard of that the outer ring will slip. Never had it happen to me but have read where other have. An OE replacement isn't expensive.

Hope that's helpful.
