Number 8 con rod............There was a gouge at the oil hole on the #8 journal. It looks like a piece of hard carbon or metal came out of the hole when it was running.
We probably could have bored it, but it was only at .004 wear, so we'll just hone it and add new rings. We are going to keep the two barrel carb, and aren't going for max HP, just a reliable daily driver.
