Don't discount "simple" stuff like exhaust banging on something, etc

Thrust bearing in the engine will knock when in gear like that. Torque converter pushing on the crank is the cause. Check the end play / total travel of the crank shaft.

Loose flexplate bolts.

No doubt about it.

Loose flexplate bolts.

yea i had to red lock tight mine as they would come loose every couple months...

once they did it right after i had did some head work and i thought something let go... worst sound/feeling in the world... check those damn converter bolts...

Hoping that loose flex bolts is all it is...

 

[416 scamp]

Great news !
That is a horrible sound , and if you haven't heard it before , you expect puddles of oil on the ground and parts hanging out of the oil pan.
Loctite blue is also a good plan....red is pretty extreme.
It will work , but sometimes likes heat to remove the bolt afterwards.
