If the distributor has been undisturbed and functional I would suggest that there may be varnish buildup on the shaft causing drag.

Clean up the shaft and install a new distributor gasket.

Verify the dist gear is not too close to the housing, binding.

Verify the distributor clamp is also installed correctly. It can be flipped upside down which may look as though it is clamping the distributor, but it is not.
Verify the bolt is not too long or missing a washer.
Some later model clamps and aftermarket pieces work only when installed 'upside down'.

To check timing chain slop;
Rotate engine to TDC.
Remove distributor cap.
Manually rotate crank backwards while watching rotor.
When rotor begins to move STOP.
Look at timing tab mark.
<5° You're OK.
>5° Start gathering parts for timing chain replacement .
>10° Timing chain should have been replaced last year.

Hold down threads are solid. I’m gunna check the lock collar before the blue. Didn’t know the collars were adjustable on the msds

If that distributor is turning in the engine while it is running I would pull it out and see how hard it is to turn that is the only thing that would make it move unless the hold down is not working period.
