This will get more responses in the Engine & Driveline forum. So let's get this moved.

On rare and hard to find or expensive engines sleeving is an option, and preferably if you sleeve one cylinder you sleeve them all, but it's not always done that way.

What caused the hole- - - -maybe a broken rod or something similar? That's a very unusual failure unless something comes totally unglued.
Have your machinist use a heavy-duty sleeve, one with a 1/8" wall thickness, not 3/32" like would normally be used to recondition a cylinder. I've sleeved race engines with holes a couple of inches in diameter in a cylinder, and got normal performance out of them.
230's have a nasty habit of developing cracks in the block along the lifter bores, so if you've got a block that's OK in that area, better hang onto it and patch that cylinder. Jerry
