Havent priced sleeves lately but it used to be around $100 per hole + boring. You could probably talk me out of my 69 340 block for less than that, or quite a few others I would guess. But hey if money is no object then go for it ! oh and pick up a stroker kit to go with it as well

I'm sure it could be done, but is the cost worth it? average cost a few years ago for sleeves was $100 a hole...not sure if that's gone up or down in the past year or so, but if you figure that, plus the cost to machine the sleeves afterwards...you're probably looking at $1,000-$1200 to turn a 318 into a 340. how much would a 340 block run you at the swap meets, online, etc.?

You really need to sonic test it first. It may be able to be bored to 4" (360 size...), but you have to have a little meat to give the sleeve some stability. I'd be concerned about leak posibilities by doing that on all 8. A std 318 type wouldnt concern me. But removing that much wall structure does.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

buy a race block. They are not that expensive.
 Even if you can get a 340 out of it, you still won't have thicker main journals, or 4-bolt mains like most race blocks have or can be fitted with.

I don't know what the industry standard is for remaining wall thickness for dry sleeves < how far you can bore to fit the sleeve> I don't think the sleeve is structurally strong by its self, the sleeves have some benefit in ware from the rings vs the cast iron block but I don't think its a cost effective way to increase bore 
That was what I am thinking... Sleeving a block with the normal type of sleeves will leave material behind to help stabilize things. Removing all the original cylinder material I think would not support the sleeve or deck well enough. Never mind the cost/return issue.
