If I was you I wouldn't be able to resist going for a tuning road trip after... 6 months of working on the car?
Planning on making it down to the strip anytime soon? Probably won't have time with faire stuff going on eh?

No time right now. I'm in Illinois right now and wont be home until Sunday night. Then I have to finish that park ave on Monday. And no open days all week. Not till the following Monday.
I understand what you are saying Dan. And I'd like for nothing else but this to solve your issue.
You thought the flex was the issue because it had some runout. Didn't end up being the issue.
You thought maybe it'* the oil pressure, however when you do an oil change on a car.. it takes a moment for the pressure to build back up. Maybe it was a long time on yours, but the info I've given you about cranking etc is all that most guys use and it works well.
Maybe if you could explain to us further I can understand the relation of false knock to dying bearings in two motors? In the reading I've done in the past, the sensors were swapped out to get more power because they were less prone to show knock. Unless you are saying motor 1 was bad luck, and motor 2 wasn't enough priming and bad luck... then the knock you see is false and motor 3 is unrelated to the other two except in seeing false knock that happened to pop up unexpectedly when motor 1 died?

Motor 1 was cam bearing, remember, the cam hit the bearing when I bumped my hand and it cause the cam to drop.
Motor 2 was a rod bearing, that was confirmed. Bad luck, bad prime.
The KR issue started well over a year ago in engine 1. I was only from time to time and only a few degrees. Mostly around 45mph in 4th gear, shifting to 3rd cleared it up. Slowly got worse over many months. Tuning seemed to clean it up and then it came back. When I decided to rebuild the cam bearing was going out and I found metal in the oil, that'* when the oil pressure dropped a bit.
Engine 2 was different. Bad pump prime, lesson learned, always use a mechanical pressure tester to verify pressure is there.
How can it be true knock? There is no part of the engine left from the first, or second engine other then the PCM and knock module.
I did have bad run out on the flex plate, I showed that with the dial indicator. Also, I had a bad vibration that I could feel and it shook the seat. That vibration is gone now.

No, vibration was gone after the last rebuild of the engine, and that used a different flex plate. There was no change when I tried a new torque converter.
