Need to find the right damper/balancer

[garrett66]

Hi all. Alright so I'm trying to time my engine but the timing marks are off a whole 2 inches from where they should be. So I guess what I think my options are would be to either get a new one or simply get a timing tape. Do you think my damper slipped? I've heard of them slipping and although I haven't dropped it it is 43 years old. Is it a problem with the damper, is it off-balance? The car will run and sounds fine but I just can't time it right since there are no marks. The engine is a 347 roller HO with a 28oz balance. I have been using the stock 289 balancer which is 28oz right? What balancer would you recommend?

If it slipped 2 inches, you'd have a noticeable vibration from it. The easiest thing to do is use timing tape.

If it has slipped, the cause is deterioration of the rubber holding the outer ring. Timing tape will get you set up, but there's no guarantee it won't move some more. These can be repaired, if you want to keep original. In your case, I would recommend switching to the heavier 68 0r 69 302 unit, or even the 289 high performance damper.

I don't think I feel any vibration from it unless it's very minor. I think Ill go ahead and put some timing tape on it and time it the best I can. By getting a heavier balancer it will keep the 28oz balance right?

Alright I got it timed. I just got a different timing light with an advance. It's timed at 35 on the light and shows 0 on the balancer. Thanks for your help

35 total's about right. Could go higher as long as the fuel will support more timing.
