Tore down my 383...

...and It appears to need a lot of work, for just having been rebuilt. Someone half-assed this, from the looks of it, beat it up, and sold it as "rebuilt." It came with the car I bought, and I knew I would be tearing it down to check; but I wasn't expecting to have to buy a crank (at least that's what it looks like to me). I swear, the more I get into this project, the more I am finding needs replacement. This is on the rearmost counterweight.View attachment 1715771907
Are you showing the crank counterweight?
It's been ground on for balance.
What's the issue?
