Does anyone have first hand experience with their Hi-Po or std. 289
damper"moving or slipping" so that the timing marks are not accurate
anymore ?

I have heard plenty of anecdotal stories about that happening, but have
never got the story from someone who experienced it first hand.

thanks.

Ray,

I've not had this problem with a Ford damper but it did happen to me while
driving a chebby. Driving down the road minding my own business when I heard a
scraping noise, really loud and seemed to slow as the truck slowed. Got the
truck ('69 C10 chebby fire truck) to the station... found out the the damper
had slipped on the rubber to the rear and was grinding against the lip of the
oil pan. For that truck the easy fix was buying a new one, chebby 350s are a
dime a dozen...

On my '64.5 I noticed that the rubber was cracked and severely deteriorated.
Hard to find dampers for a 260 so I had mine rebuilt. Don't have the info
with me but I could get it... wasn't very cheap though.

Z. Ray,

I'll have to come out of the closet for this one.
I had this happen to me years ago (during my short stint
when I was unhappy w/ Ford products - %^&* Mustang II)
I had a '78 zuh, zuh, Z-28 w/ a 350. There, I said it!

It was so long ago, I don't even remember what the symptoms
were. The car either ran real rough, make noises, or it wouldn't
run at all. Anyway, it was the harmonic balancer.

Regards,
Rand... ummm I mean Mike, yea, that's my name, Mike Smith.

It happened on my 65 when the rubber (due to old age) was allowing some
movement, Not much, but enough to throw timing off a bit. Have you been able to
verify TDC and compare it to "0"?

Yes, it can/will happen when the factory bond ages. If you confirm that
it's moved, you need to rebuild or replace the damper immediately. You can
send it to Damper Dudes in CA and it'll come back better than new for less
than a new one. On a stock style damper, I paint 4 red lines radially
across the ring, bond and hub (at 90 degree intervals) so that I have an
immediate indication of any problem. And I check them regularly, since we
race a lot.
