Timing marks aligned together, while the manual calls for them to be seven links apart (12 pins). Timing chain was reset and compression tested again. It's up at 110 where it should be after a rebuild.
We'll close up the engine and re-install everything that was removed today on Thursday. Hoping to fire it up on Friday or this weekend.
Congratulations! Always nice to find the solution, even if it did drive you crazy for a while. I hope the engine builder compensated you for your headaches or has a least learned the lesson. Some of us just don't like to read directions sometimes...
Not to this interesting thread, but anyone know or speculate why Ford broke from normal industry standard protocol when they went into the OHV engines? They went back std with small blocks and the FE series.

Not exactly on subject, but I look at this picture, I do some work around cranes here and there, and I see "LINKBELT FMC" on that cam gear.
I feel a cross between work and play...I think I need to find a councelor...I don't like it.
On a positive note glad you figured it out!
Another classic case of...if you want to done right, do it yourself.
That's just my excuse for not being able to pay anyone to do anything for me..
Hang in there by the towel tag Ilya! You are almost there buddy!
Let me show my ignorance (happens a lot on here).
I look at that picture of the timing gear & I don't see a thing about timing
marks lining up. What are you looking at on that pic that jumps out at you? Just watching & learning....
A camshaft has to be in coordinated time with the crankshaft rotation so the valves open and close at the proper time compared to their piston position. The cam usually is designed to turn at 1/2 the crankshaft speed. To drive the camshaft and keep it in proper time a timing chain or toothed belt or gears are used.
To orient the cam drive at the proper relationship some sort of marker is used. If you look closely at the picture above you will see a "o" stamped on the crank gear and the cam gear (harder to see on the cam gear, look on the tooth below the "e" in link belt)
On most engines the two marks are aligned with each other when the cam gear is bolted in place to set the timing. I suspect Ford in his famous frugality (read CHEAP!) decided to use a gear already in inventory from and marked for another engine on this motor. To properly time this engine the timing marks must be offset by 7 teeth. If you don't carefully read the manual, most mechanics would set the marks in alignment, as done on almost all other engines.
Two lessons to be learned: 1. Always read the directions, no matter how many times you've done something before. 2. Ford often bucked the system to use parts already in inventory to save money.
Thanks Guys - I now see the faint circles that line up. I've seen timing marks before - but they were lines & I was looking while shining a timing light on them. I continue my truck education daily on here!
