I know timing. I have been messing with timing for how long now? 30 plus years my friend! So have a little confidence in my ability to time an engine.

I know how the engine timed with the dots NOT lined up. It timed normally. Get it close so it will start and idle then fine tune it. Works every single time. I have a bunch of old cars and trucks. They are all timed like that and they are run great.

When I lined up the dots and tried to time it I could get it to start but it would not fine tune. The timing was always off no matter how much I fine tuned it.
After a half an hour of fine adjusting I knew the move I made was wrong.

Can you see now that lining the dots up was the wrong move?

Thanks for your help.
Cam advanced like it was the engine didn't run right at all except for idle.

Cam advanced like it was had valve events happening way too early.

Advanced valve events had the engine pulling 2~3 times the idle vacuum it does now.

Doesn't matter how much you "fine tune" ignition timing, with the distributor, when the carburetor adjustment for idle can't even be close to right.

Your first timing chain pic showed crank gear was off at least two teeth. That is not a degreed cam it was some ones mistake. As posted earlier...Does appear that you have it right now.
