You found the right guy.

Looks like is spun a rod bearing, which means that rod will need work and more than likely the crank as well. Rods spinning a bearing no big deal crank spin a main that gets to be pricey as a line bore is needed etc. Make sure you number the rods and rods caps, as well the mains ...do not mix them up. As well I have found that a digital camera rocks for things like this you cannot take too many pictures. Looking good, I would not do any machine work or buy any parts until block is magnafluxed maybe even the heads as well... I do not think parts are going to be easy to find so take your time.

Oh believe me I have more pics than youd want to see. I used my customary way (way I was taught) of marking the side of the rod cap with a punch, and then the same side of the rod, that way number of dots and sides match up. But then I was happy to see that they are factory marked; on one side of the rod and cap it has a number stamped. Pretty cool.

The rod is going to need work and the crank is going to need a lot of work

You have two good threads going on this.

How's this coming? Any updates?

The account has been suspended so until that is resolved there will be no updates.

I didn't notice that. What a shame.

Maybe an admin will pop in and let us know what's what. Maybe it just needs downgrading to a regular account?

Wish this would have continued since my V-6 will be getting some attention sometime soon..

Wow, super nice offer. I don't think the mod's suspend accounts for just not re-upping do they? I figured they would just downgrade the account automatically.
