Terry could you describe briefly the procedure you're using? I've been watching this thread and am interested in the outcome. Thanks Joe

Mark,Tried the one tooth off, did not help.Had degree bushing set at zero. Checked my degree wheel readings, first reading was 56 went to other reading it was164, total is220 divided is 110, same as all my readings. Never had a problem degreeing before.

I've never seen it happen, but I suppose it is possible that the bushing does not have any offset in it. When you loosen the bolts and turn the adjuster bushing, can you actually see the bolts move in the center of the gear? I have the same type timing set on one of our 427 engines, it works just fine. I am changing to the fast adjust, I like it better, but the hex adjust works fine.

Alan, yes you can see the bolts moving back and forth when you move the bushing. I am begging to wonder if the stud that the cam bushing sits on is bent, and is causing binding problems when I tighten it back up.

It would be hard to get a really bent dowel pin into the bushing.

Did you unscrewed the tip out of your Dial indicator so it will Lay flat on your Lifter?

Terry,at what reading from max lobe lift are you taking your readings? I have never heard of moving gear 1 entire tooth and not seeing a different reading,perhaps your not coming far enough back from the "nose" of the lobe to get a real number, just a thought. Joe

If you get the same result by doing this you clearly built in a "mistake" in your doings..same as Bill K i had my moments when i just was too tired...
