Ok a few day ago(last friday) I got into town and was at a friends house. When I got there everyone was out so I gave it a good rev and let the exhaust tell everyone I was home. But after this I heard a dinging sound. I imediately thought the harmonic balancer. But took off the belt and found (or so I thought) the water pump locked up. I replaced it. But when i tried to spin the the old water pump it was fine. The ding was the HB and water pump pulley hitting. So I checked the timing to see if maybe the HB spun. Its set at 11* and when i check the timging i set the gun to 11* but no mark. So i turned it down 1* at a time and finally found the 11* mark on the HB with the gun on 8*. I dont understand? Should I replace the HB and see or what? Please help need my mustang back up and running!

Have you looked a the balancer while the engine was running? Did it seem to be wobbling? If so then the elastomeric damper is coming disbonded from either the crank side or the ouside of the damper.

It appears to be wobbling ever so slightly. What would cause the timeing to read the way it is?

Then you need to replace it. The outer ring has already spun slightly and that's why the timing reading is off, and is also the reason why it has a slight wobble.
When my harmonic balancer failed on my 95 GT it spun so the timing marks were off. If I tryed to time the car by the timing marks it wouldnt run. When I finally took it off it came off in 2 pieces. Sounds like the same thing is happening to yours.
ok im going to order a new one today and try to get it on there. Ill let you guys know. I think this may be whats been causeing my vibration in the car. No another thing when I was checking the timing the mark would be on a few times then off once then on a few times then off. Is this anything to worry about or could it just be a miss in the light?

My car also was shaking from the bad harmonic balancer. Not sure if my harmonic balancer caused it but after I replaced it my engine blew up. I think the last person who owned my car had NOS on it.
It isn't the light, it's the balancer failing why the timing would look to be jumping around. The balancer marks are actually moving, not the timing itself.
It'd also explain the vibration, it's not doing what it's real job is which is to quell those vibrations. Get a new one on there, it should feel better.
Going with another stock balancer? Why not go with at least a Pioneer balancer? Not all balancers are the same.

I was looking at a pioneer one but none of the auto parts stores near me had them and i need my stang back. So i just opted for the oem replacement. Im replacing the motor in a few onths anyway.

Change it as soon as possible! The balancer is supposed to take out harmful and performance robbing vibrations! Now it is actually inducing them into your bottom end! You dont want to end up with a cracked crankshaft!
Glad you were able to isolate the issue!

Maybe you oughta look at getting something a little more robust that stock.
Got it finished today Threw the timing light on it and the marks were dead on. The rubber on the old one was dry and cracked and had play in it. Took it for a test drive and she runs better than when I got it. (About 3 or 4 months ago) I think this has been a problem for a while. I'm glad im rebuilding soon. Im not sure how extensive the damage is. Im sure its been gone or at least going out for as long as I've had the car. Being as it has more power than ever. I mean i spun straight through 1st and 2nd on a sticky new road I usually stick to and go. Feels good to have her back up!
Did find out my front main seal is leaking though. Not bad. But still.

Harmonic Balancer Bad?
