Darton MID sleeve will cost you over $3K and some machining will be needed after. If you have a LS3 block, take a look at ERL's offerings. Complete dry sleeve short block around $5K. If you have a few more bucks and are serious about FI in the future, look at the Superdeck. Put a set of MAST LS7 heads on top and you will have a foundation for whatever you want in the future.
Lots of fun spending other folks money.

Its about $1,900 for the sleeves to dry sleeve a block, machine work, stress relief, installation and decking. Boring, honing, align honing runs about $600 additional.
You need to send them your pistons, main and head hardware so they can do the finish hone work.
Thats everything to prep the block for assembly.
Do it....you wish you had if you don't.

were having the block sleeved, (apparently the stroke is really big for the (stock sleev and causes the piston exposure including part of the rings and in time will cause premature oil burn and quicker intervals of rebuild.)
so yes were having it sleeved but keeping the same bore.

hope the guy down the road knows what he's doing. Does he have the right equipment like a cnc machine or is just gonna hog them out with a die grinder? There is a weak spot in the L92/LS3 heads somewhere.... can't remember where but if to much material is taken out than you will have a very good chance of failure. Drops a valve i believe. It's something to do with the spring pocket that protrudes down into the runners. Someone help me out if you know what i'm talking about.
I wouldnt let bob down the street touch my heads, send them off to WCCH, or TEA and have it done right.
