Ls3 block
They have "specials" such as this from time to time, you need to ask a GOOD counter man.

Gm doesnt make "rough bore" blocks and ok them for sale. They are normally mismachined in any number of ways and only a very competent machine shop could find all the issues and correct them and sometimes lead to odd parts sourcing to make them work right.

The GM dealer will ALWAYS take a return if requested.
The Spoolin question : Call Tony (#146) at Precision Engine Parts (PEP) in Las Vegas.
He is a great help to ALL.

As for any gm dealer...no.
Seriously stop giving out such terrible info. This comes up on a ln internet search and someone uses a blem block thats all messed up because you say so, they can blame you.
This isnt ebay, Craigslist, or amazon. The sponsors on here are held to a higher standard of parts and info they contribute. Budget builds are easy but using known wrong or bad parts is not in line with that.
As they say hold what you got so you can get what you want, Not need. 300 here 300 there and you got it.
Ws6store, I appreciate the time, info and affordable pricing you are bringing to this site. I plan on buying a couple rebuild kits from you as your pricing doesn't make it worth me searching for the best deals. I fully thought they would be blem blocks but that's not to say they are junk. What is usable with little to no work is totally different than buying a 30k+ car or truck with said blem in it. All manufacturing has there blems and sells them accordingly also. The biggest one for this site is the Ati balancer, 430+ new or get the blem when it pops up on eBay for 250 shipped. One could argue the harmonic balancer is one of the most important parts on a build but lots of people still using the blems.
Some cam tunnels were way off. Some decks were 9.24 on one side and .920 or less on the other. The list goes on. Some are worth it but still take an extra 200-300+ in machine work so pretty soon you are at the cost of a new block. And finding a competent machine shop to do all that seems like a fleeting possibility now days.
