Easy enough to test to see if the camshaft is in one piece - remove the
valve covers and turn the engine by hand and watch the valves open and
close (or not open and close). Then you can also check if the push rods
are still in one piece.
Do you think that you might have sucked a carb bit into a cylinder?
Happened on my long-gone '67 Bug, the accelerator pump nozzle that
squirted gas down the carb barrel dislodged itself and was sucked into a
cylinder. Made a horrendous noise when we were on a trip far away from
home. Then magically the noise disappeared as the beat-up brass bit was
shot out an exhaust valve. You'll have to pull the head to have a look
inside unless you have one of the boroscope gadgets.

No stethoscope, can try to find one, but my best guess now is it sounded like it was coming from behind the top most largest timing gear, which I gather is the camshaft? I was trying to make sure the valve timing was on also, there's a white mark on the largest gear, but I can't find a mark on the middle gear, wonder if the valve timing somehow skipped a tooth? Also looked like that large gear was wobbling a bit, could have been just the angle I was looking but I thought it was wobbling a bit. Also figured it couldn't be the gen as it wasn't connected and I still got that clacking. I wonder how an engine with a mere 6100 miles could have developed a mechanical problem so soon in it's life, I can see gaskets and such from sitting but not mechanical, who knows.....
