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.

Thats only way to go..smart move. Although Butler is good..I hate to say this but you can’t trust any you get. I’ve also learn not to trust anything done by machine shops or I should don’t take it for granted. I know it sucks !
