This is a CE LS6/L88 4 bolt block. I've had it for years and was planning on building it but never got to the project. There is one sleeve in the # 6 and a crack in # 4 which will need a sleeve. Block was magged and there is a small crack coolant beck port  (shown in photo and highlighted in blue) which shouldn't be an issue. A few threads will need inserts. The bores are is .125 over which these blocks could handle since they were known to have thick cylinder walls.  It's a good candidate to sleeve all 8 to standard bore too. It's a very desirable block and worth the effort to bring it back or you could spend $3k plus for a clean block and hope it doesn't have issues.  

Buyer responsible for shipping from the 12209 area. Willing to drop at a shipper in the Albany NY area and if you want it in a plastic crate  I can do so for an extra $75. 

Please ask questions before bidding.
