For larger CID reasons or just to save the block?
IIRC there was someone by the name of Hoover(something) on CZ28.com a few years ago that sleeved a block to do a 420 or 427cid LTx. What I remember is it working alright for the application, however it was tedious costly. I vaguely remember the car running well and was driven often

My #1 is sleeved after I had a piston disintegrate and the wrist pin tear into the cylinder wall. It came out fine and haven't had an issue, but the sleeve might not go far enough down for a very large stroke application, it only goes about 3/4 of the way down the cylinder.
Although I have a feeling you're talking about sleeving to increase cu in, not repair.

I had a sleeve added to a motor that did pedestrian duty for years with no issues. My machinist said they dont go all the way down because of structural rigidity, and the process is very delicate, have to heat the block before pressing the sleeve in. I went .030 over and he bored that cylender (with a large gash from a wrist pin) i'm not sure how much, and then had to lip it if I remember right and then press it in.

I've seen Fred talk about some guy from somewhere sleeve an LT1 for a 427ci everytime a "how big can you go with an LT1" thread pops up but who know's if its really true.
Hell, I've never even seen pics of those RARE "big cube" LT1 blocks that came from GM so long ago.

From what I've seen they all moved here and LTxtech.com.

Dart backing out of the "big bore LT1" pissed A LOT of people off that day. Especially after leading us on practically for a whole year. Had they produced that block I would have been all over it like white on rice.
