Default Re: Nocking at high RPMs

So after some valve adjustment (a few needed small adjustment), learning how to use a timing light (it was at 10deg, turned back to 6ish) and new plugs, wires, cap, rotor and points, it starts quicker and runs smother at idle .... Buuuut no change in the nock at high RPM under load.

I'm resigned to the diagnosis that I've burned a rod bearing.

Stay tuned for panic posts about pulling a Big block V6 in the driveway!
And the subsequent need for gaskets and bearings!
