Isn't TDC defined as #1 piston at the top of the cylinder with both valves closed?
This was a total rebuild with a different flywheel, cam, lifters, crankshaft grind etc.
I can tell you if i set the timing on the ball...the engine barely runs. It is set advanced past the "c" (could be what's left of my UDC) on the fly wheel.
It could be because it is a different flywheel. but with the #1 piston at the top of the cylinder the pointer is no where near the ball or other markings on the flywheel.
I will dial the timing back in tiny increments and see if I get any improvement. If it ever stops raining here,
