Could me engine timing be inaccurate

Thanks for looking to help me out. I really appreciate it. I have a crate blueprint 350 https://blueprintengines.com/product...ed-front-drive

I'm worried I have not done the timing process correctly.

1. I pulled all the plugs and put a paper towel ball in plug hole 1.
2. I turned the engine with a socket wrench and after a few turns the ball shot out.
3. I saw on the harmonic balancer this was top dead zero per the marking.
4. I dropped the distributer and as it lowered it turned ~50 degrees clockwise. I was worried this was too much of a rotation because I have never done this before.
5. I raised the distributer, rotated it ~55 degrees counter clockwise. I lowered the distributor in the exact same degree orientation I have seen in a dozen mechanic videos and it rotated itself ~55 degrees clockwise again just like last time.
6. I started the engine. At ~2500 RPM with my timing light I rotated the distribuer to show 36 degrees advanced on the harmonic balancer which is the value in my documentation.

Is there anyway possible that my engine is not actually at 36 degrees advanced?
