Depends upon the type of sleeve.
There are gaps between each cylinder in the water jacket. The cylinder walls are nominally 0.160" thick. A block that has been bored 0.040 oversize still has cylinder walls that are nominally 0.140 thick. The cylinder walls may be too thin to handle thrust and combustion pressure, but the block's structural integrity is not in question at that point. If I can dry sleeve one cylinder, I can dry sleeve all eight. A 0.040 oversize block having no other issues would be a wonderful candidate for such machine work. The sleeves are much higher in quality and strength than the original casting. The resultant block would be much better in terms of cylinder wall strength and cylinder wall wear resistance than the original block.
However, installing wet sleeves, which means removal of the cast cylinders in total, does indeed weaken the structure of the block and is a completely different circumstance.
I hope all this makes sense, or perhaps it will give the curious something to investigate. There are some wonderful dry sleeves on the market.
By comparison to medicine, this is child's play.
If you are a sixty something year old surgeon, you can not procede on forty year old technology. Who cares with a machinest?
This is a relatively small advancement in technology. One must question a machinest that says 8 sleeves can't be done, when apparently this has been getting done for at least ten years.
Find another machinist. As a customer you MUST have more then a basic knowledge.
You just can't pick up Hot Rod magazine, say I want to build an all "unobtanium" 5000 cubic inch engine like on the cover and have not a clue on how it gets done.
8 sleeved blocks have been around for a number of years. I don't know how to do it. I do know how to find a machinist that does.
I personally wouldn't junk that block.
