Sorry for slightly jacking your thread here Cannibal, but maybe if somebody in the know responds here, they can answer this too...
On the Darton page they mention that your "local machine shop" can do the machine work needed to fit the sleeves. Do these sleeves still require a CNC machine to fit them?

I did a lot of research on this before deciding to have TSP build me a 383 stroker. Here's what I have found:
The Darton block takes several months to get (from Darton).
They have had o-ring problems in the past.
Scouring the Internet, I could only find two LS1's that actually have had them and put some miles on them. One of them has blown-up (don't know if it's block related). The other is on this board and has had some issues smoking based on his recent posts (again I don't know if it's block related). There may be several out there without any issues. I just haven't been able to find them in my quest for information.

I still really can't sway myself from buying the C5R block. It's the only fool-proof way to go for big cubes, IMO. Yes, it does cost $6125 shipped to my door but that's far worth it to me for never having to worry about sleeves, etc.

MMS is putting a Darton wet sleeved 427 in my car. Should be up and running by the end of next week. It did take them about 8 months to get the block from Darton. It has the new "revised" sleeves. The outside of the sleeves have ridges so the coolant can travel between the overlapping portions of the sleeves. The ridges also create more surface area to help keep everything cool. It better be pretty darn strong to handle all the extra air we're giving it! 
Here are some pics (bigger ones are on my website).

I am also having a Darton wet sleeve 427 being built. I guess like the post goes, everyone is just getting theres now, or still in the process. Just to make all of you feel better about waiting, I waited for my block also. I got it after about 4 months. I am 99% sure that Darton themselves sleeved my block. If not then I wasnt told by JPR who was putting the sleeves IN the block. Regardless I was told by JPR that he block had a 6 moth warranty. I dont think that will help me much since I will get the motor back end Nov, then spend Dec, Jan, Feb, and March waiting aroung to race. If a problem happens before I even Start racing, then I would be pissed. I cant really contribute much else. Lets hope this works for ALL our sakes. TTT

LEVI,
If your going to go for it i don't see how you could wrong with LPE's Darton Sleeve as you know they have r&d the crap out of their new darton set up and they are offering it for sale now with a warranty, etc. for aobut 1/2 the price of the C5r block. That would seem like a real logical decsion to me and a choice that was not available to me a couple of months ago when i decided to go with the C5R block which is WAY TO EXPENSIVE in my honest opinion!

How many big bore people are actually running with no issues. Just about everyone I know of that has a resleeved block has had problems. The shops are taking care of the problems but no one will talk about it because they are afraid that they won't get their issues resolved. I feel bad for the people because no one wants to talk about it. I seriously doubt that if you have a big bore 427 and you haven't had any problems, you would go spend $6,000 + the cost of a rebuild so you could sleep at night. Get real... I am not lashing out at anyone so please don't take this wrong, but it is wrong no one will say the real issues here. I am so glad I listened to a certain person and did a Stroker instead. What gets me is that GM can produce a block with sleeves and have no issues with dropped sleeves. Maybe they should produce an optional LS6 4.100 bore block.

issues? what kind of issues? i m about to get my block resleeved, but i am not ready to deal with ISSUES? please give advise as to what i can do to avoid problems. i am thinking of doing the 396 all bore, but if resleeved blocks are not to reliable, i would rather just go the 346ci forged route. any advise would be appreciated.

I can't wait for the day the process has been perfected. I will wait a year or two and see. I would love to pair up a 4.125 bore with pistons along with my Lunati Forged 4.00 crank and Lunati rods.
