I'm Awesome
I have had a very minor vibration in this that was getting much worse with the torque converter bolted up. Well I feel dumb at this moment.
Completely missed that the TCI flexplate I had and used is for an internally balanced 1-piece rear seal engine. I did not even realize that was a thing and somehow completely missed the missing counterweight when I threw it on before dropping the engine in. Here I was about to rotate the torque converter and noticed it was missing the counter weight. Good thing I have a spare SBC 4L80E flexplate hanging on the wall that matches the TH400s 11.5" converter bolt circle. Missing counterweight will cause a vibration all right and it gets 10x worse with the converter bolted up.
