Thank you for your feedback. My fault I have a 305E engine. 1965 GMC 1500
@AZKen
Please explain in detail.
If I understand what you did...
1. You removed the cap?
Yes
2. You rotated the crankshaft (CW) by hand until both cylinder 1 valves were closed and the rockers were loose?
The rockers are loose; I can move them by hand. Crankshaft position: 1TDC
3. Then you observed the rotor position was at cylinder 6?
Yes, 6 in the photo.
4. Then you rotated the crankshaft again? CW or CCW?
When I stand in front of the engine CCW from 1TDC to the 10° mark, and when I reach this point, I get a spark on cylinder 6 (with the cap on the distri) because the rotor is in position 6.

I tried to turn the rotor on the distributor (while it was installed), but it won't move. It's stuck. There's no movement against a spring or springing back. I assume it should look like this:
I'll check the mechanism of the distri. Perhaps as you said the finger is actually locked in its maximum position.

Many thanks for your help and photos. Yes, I have this 1TDS marking on my engine/pulley. The piston on the 1 cylinder is also in its top position (up) and the valves are closed.
