i posed a similar question a couple weeks ago, i had wanted to make my ls1 400+ci, but the responses i got said that the stock block and sleeves can only be bored and stroked to 383, but you can resleeve your block to get your desired displacement. but they said that it is very pricey and a hassle and sometimes problems can arise from it. i was told it would be cheaper to either get a 6.0L iron block, or an ls2 block

Very expensive to resleeve and you will get mixed results. Mine was resleeved in Germany to a 4.125" bore using Volvo Diesel engine sleeves. They always seeped a little water into the oil. A few machine shops recommended I use Moroso Ceramic engine seal but I never got around to it. By the time you get it resleeved you could have almost bought a new LSX block.

Here are your options:
1.get Ls7 Block.
2.Get L92 or LS3 Block And With 4.07 Bore x4.1 Stroke =427ci (I wouldn't use N2O or Forced Induction)
3.Get Lsx short Deck block and get safely to 454ci.
4.Get Warhawk block.
5.Get ERL block.
6.Get C5R Block
7.Get DART Block (WAY expensive)
8.Resleve your block but find some one who knows what he is doing to Resleve it for you.

LS1 block sleeving The LS1 block is a very good candidate for Darton MID sleeves. There are two versions available, 4.125" to 4.160" and 4.175" to 4.200" bore. All Darton liners are now 5.800" long.
I am one of the patent holders of the MID sleeve and have done dozens of MID installations in the LS blocks, close to a thousand MID installs in all makes of blocks. I have two LS1 blocks here now lined up to do shortly.
Expense is relative. The sleeves and machining process is not cheap but the end product is very reliable if done correctly. There is no chance of the sleeves sinking or cracking as with some of the other options.
The dry sleeved LS2 is more cost effective for normally aspirated applications if you already have a block or can find an inexpensive used one.
