So, after lots of internet sleuthing, the consensus seems to be that the rod bolts and 4 inner main bolts are reusable because they are actually TTAngle not TTY. Sloppy mechanics even re-uses the head bolts which definitely are TTY.

I think I'm going to knock all the pistons out, clean the deck, hone it, ring gap it, clean it, and slap it back together. If the rod bearings look ok, I probably will just leave the mains alone.

I like your thinking. Take some photos to share please.

Do you have the beefier connecting rods? I think somewhere in 04 or so all LS engines got them?

It shouldn't because it has the 2 short head bolts so the block is 03 or earlier. I'll get pics of them.

The clue is in the title....

So both of the rod caps I identified as loose, the bearing didn't come out with the cap. Doesn't look like it spun.

These bearings look new other than some light scoring. They are marked GM STD, so I don't think they are undersized. I'm going to pick up some brake clean and see if the parts store has plasti-gauge.

I think on a motor that is going to see boost it's probably better to be too loose than too tight, but way too loose is probably no bueno.

The crankshaft rod journals looks pretty good.

How much clearance are you getting for the piston rings?

I filed them to .028" +/-. They were probably .015-.020 before.

A loose motor is a happy motor, especially if you're boosting.

...oh I forgot to ask on my last post if you were planning on checking bearing clearances with plastiguage?

Sorry for being so nosy. I've got one of these engines torn apart myself and was trying to get it machined and put back together.

I started too and then I was like ... meh ... good enough.

If I ever have a problem I'm going to say it's going to be the #3 rod bearing. I could only torque it to 49 ft-lbs. Everything else got 50, but that one bolt would not tighten anymore and gave me that if you turn it anymore it's going to break or strip feeling.
