How many cubes can you get?

How many cubes can you get?
I am looking to stroke my motor out. How many cubes can you stroke it out too with out having to bore the thing out and how many cubes can you get if you bore it out.

You can put a 4 inch stroke in an LS1.. giving you iirc 382 cubes with the 3.905 bore. You could go crazy and bore it all the way out and get like.. a 383 with 3.910 bore, but that's not recommended.

Commonly, without sleeving (like everyone else has said) a 382ci engine is possible by just lengthening the stroke. With resleeving the block, you can commonly go as high as 454/5ci although I've seen some slightly larger builds in the past - don't know specifics but it has been done on occasion. Not sure I could see much good reason to go above 454 except for the bragging rights. You can do A LOT with 454ci, even N/A.

More than it would cost to get an lsx block or an ls7 block depending on whether you want alum. or iron. I was thinking of resleeving mine but to do it right its gonna cost around 2500-3000 dollars, the lsx block is only like $1800, and the ls7 block is about the same maybe a little less.

Max engine size
Darton does indeed have an MID sleeve for both the LS1 and LS2 LS7 blocks that will go to 4.200" bore. The LS7 dry liner suitable for LS2 and LS7 blocks will go to 4.190" bore normally aspirated.
All Darton sleeves are now 5.800" long to allow strokes to 4.250". At 4.200" bore and 4.250" stroke you end up with 471 cubic inches.
A lot of folks may not realize that the LSX block has short cylinder walls, not to mention they weigh twice what the aluminum block weighs.
The basic cost of dry sleeving either the LS2 or LS7 blocks is $1,550.

I would say the max I would do is a 4.000" stroke. 383s are typically the biggest the normal person goes, but I have seen higher. Sleeving the block just isn't worth it IMO, you can get an LS2 block for MUCH cheaper than that.
