The crank is a cast Eagle unit from Butler. I’m not sure if they check them for straightness before they ship them out. I would imagine they do, but things happen.
I’m thinking I’ll pull it l, get it torn down again and have our local Pontiac builder take a look at the block and the crank.

I had a Eagle cast crank once. Sent it to Dan Whitmore and he checked it from one end to the other.
It was bent .004 and has .001 tapper on journals along with a very rough thrust surface. Had to have it straightened, cut .010-,010 and polished.
Bet its the crank,
