What we've been talking about for a few pages now is piston slap. We already know it's not the flexplate. You found nothing wrong with it other than oblong/worn holes and that doesn't cause a noise.
Windage tray? Maybe but I doubt it. We already know the piston mishap with this engine, having some in backwards and one in the correct way, so that alone is a red flag to most of us. Someone dropped the ball there whenever it had been messed with the first time and should have been addressed when you found it. Unfortunately, I feel that things need to come back apart completely and refreshed properly.
Yes, a video would really help everyone. There are many of us here that have heard a lot of strange things about engines. Without a video we can only guess, but from descriptions you've stated up to this point, there isn't much left to guess at and it starts to narrow things down to what some of us have mentioned already. Fingers crossed it's simple, but at this point I'm thinking it's more involved.

I have to ask, why would a Piston being installed as long as it has and under my own torture that I put on this Engine endure to 130 mph where I found all the internal problems and solved them over time. In the beginning the Rocker stud nut was cracked and I replaced them with 7/16" screw- in studs. While there, we installed the Johnson Hydraulic Lifters, a new oil pump and HD Chrome moly Push Rods, had a new timing Gear and dual chain.
The # 886 Cam was worn out, but who knew at that time. I had the Tri-power Carbs. completely rebuilt, by us OfCourse, using genuine Rochester parts that would have come in these Carbs. from the factory. We installed the 1/2" spacers under the Rochester's too. We had Air Induction as well and the Carbs. are up-jetted to a 428 ci Motor. So, this combo. at 70 mph, stomp on it the secondaries come in with the kickdown gear and I launch from 90mph to 120 mph throwing me back into the seat and moves slowly to 130 mph tops. Now you all tell me that I need to build the bottom end today, now?
I tell you this Engine is a monster and I still carry extra weight in the trunk due to the posi-traction W/ four-wheel Disc Brakes.
