Hmmm, I'm going to bet he's going to go through the sleeve. Didn't SDPC sonic test one of their original blocks and found that they couldn't tell the difference between sleeves and the block? Therefore it would appear to go .060 over but that would actually be the block not the sleeve.
I am almost positive Darton is working on fitting there sleeves to this block. No difference in this and the LS6 though same bore space so you will not get more than 4.160" bore.

What would the differences be for a LS2 sleeve versus a LS1/LS6 sleeve? Isn't the block identicle except for some oil passages and bosses in the valley area? I would expect the sleeves that are currently available for the LS1/LS6 to work.

Just wait til GM is selling 7.0 blocks
Next yr u will be able to buy a 427 LS2 shortblock for 4500 complete with good internals.
Darton and the C5R blocks better drop cause no one is gonna pay 3 to 6 k just for an empty block.

Ls2 I have not cut open an LS2 block to see if the current Darton MID sleeves will work or not. We are looking for a warrantee block for this purpose.
Darton is coming out shortly with a new sleeve that will safely go to 4.200" bore. The blanks for these sleeves should be in stock within a couple of months.
I don't think the new LS7 short block will sell for $4,500. The titanium connecting rods alone will run close to that price from GM.

Maybe in 5 or 6 years when the LS3/LS8 comes out

It's not the extra cubes, but the exotic internals and the fact each and every engine is hand built specially trained builders. If the Z06 is priced in the $65K range, availability will be way out there. I'm sure GM will offer the bare block, which be a whole different story.
