is the ls1 sleved?
if you have darton sleeves installed you can do up to a 454ci, but it is expensive to have done. sleeves will run you about 1200-1300, machine work close to the same, plus you need a block to send them, then you have shipping. figure approx $3000 for a sleeved block once you add it all up. also if planning to buy a block for sleeving DO NOT buy an LS6 block, buy an LS1 block
now if you want to convert over to the LS2 setup they are easier and less expensive to sleeve.

Factory sleeves are usually made from gray cast iron for reasons of cost. Some have used or still use either a metal matrix composite wall (Honda) or nickle silicon carbide (nikasil) - BMW, Ferrari, etc.
Darton sleeves are made from high strength ductile iron. The material is expensive and machining it is not easy.
There is no inexpensive solution to sleeving the LS1 and LS6 blocks. Replacement dry liners have a tendency to fail in these blocks. That is the reason Darton designed the wet liner - MID sleeve. This design eliminates problems with sleeves dropping or leaking. But the sleeves and installation are not low cost by any means.
The LS2 block however can be dry sleeved. It is made differently from the earlier blocks. I had Darton make LS2 specific replacement ductile iron sleeves that will take the LS2 to 4.125" + bore size.
If you are just looking to go to a 4" bore without high boost or heavy nitrous, I recommend you just go out and buy yourself a new LS2 block from Scoggin Dickey. That would be the least expensive solution.

is it good it lloks like a dry one i guess?
If you are looking for a aftermarket solution for more cubes, then Steve at RED is the man to talk to. He posted on your first page. He is the co-inventor of these Darton sleeves, and really the only one I trust to do any type of sleeving work. The LS-1 MID (wet) sleeves are rather expensive and require speacial parts to work, but when used correctly, can handle a boat load of power. For the power your looking at, I'd use a LS-2 dry sleeve. They have 2 versions. One can accomodate up to a 4.150" safe bore and the other (LS7 sleeve) which can go to 4.190" I believe. The LS7 sleeve can be used in the LS2 block. The cheapest way without sleeving is to use the Stock LS2 block like steve mentioned. They have a 4" bore from the factory, and I've seen some bore them to 4.030", but I wouldn't.
Sleeving these motors is a tedious task and most machine shops don't have the tools to do the job correctlly. In most cases, you end up with a dropped sleeve and end up wasting more money then you would have if you would have done it correctlly the first time. If you need sleeving, talk to Steve about your best option, but the stuff I posted above should set you in the right direction
is it good it lloks like a dry one i guess?
if can be isnatlled on LS1 and making a bore of 4.15" it would be great...
any feed back please for some one has used before the melling sleeve...
