460 Knock

Qas on here a while back writing about my low oil pressure on a, 94 F-250 460. Ran it for a while with 15w-50 oil but it knocked at high RPM so rather than throw a rod, I just put new main and rod bearings in. I put assembly lube on everything, torqued all the caps to spec and primed the oil pump. And this is the result,
. Any advice? I'm pretty done with this thing now.

Video wasn't really long enough to get a general idea on direction of the noise...
But it sounded like exhaust or lifter collapsed.

Is it louder top of engine, bottom of engine, or near the exhaust manifolds?

It's definetely rod or main bearings, I just didn't want to believe it yesterday. I can hear it clunk in the pan when I turn off the ignition. Looks like I'll tear her down one more time

The only way to fix it properly is remove the engine, disassemble it, and have the crankshaft turned. I don't mean to be critical but that's just the way it is.
