Hey guys, I bought a V6 motor from an 86' firebird a while back to swap into my camaro after the current V6 seemingly crapped out. After tearing apart the new motor, I got the following pics of the bottom end. Is this too far gone? Can it be fixed? I'm not expert on actual diagnoses so I'm just wondering. There's also quite a few score marks on the cylinder walls and dammage to a few of the pistons. Alternatively would it be possible to easily source a good block for cheap? Below are the pics. It's the oiling passages right between the cam and the crank. Although not fully clear in the pics, the outermost ones on either end are really jagged as if something hit them.

That's just the way the blocks are cast. Send it.

 

You need to really cleanup the block for better assessment. The cast holes with the sharp edges ore just flashing from the casting process. I would of thought they would of cleaned those up before assembly. If the rest of the block checks out I would go around and debur all of those spots where you see the metal edges overhanging the hole. With the dirt in cylinders and on the bearings, it looks rough, thats why you need to clean them block better. You didn't say how many miles or what kind of damage on the pistons, or were there metal shavings in the oil. If the cylinder really is scored, you may have to do an oversize bore which would require new pistons. Were you planning to just cleanup existing pistons, re-ring them and just do a quick hone on the cylinders? There's to many variables and not enough information to give you a straight answer.
