The S8 was done from the top down--essentially a gigantous drill press like milling machine that bored the oversize. After that was done, the block was moved away from the boring bit and had the cylinder cleaning and prep. Sleeve was inserted in some other contraption which went down in the bore then clamped and expanded someway to center the sleeve. Just a matter of pushing a button and the sleeve went down slick as you could want.. The actual work only took maybe an hour but there was a wait for the cleaning and sealer to get ready and temp to stabilize before the final boring or honing. I was expecting it to be a lot more involved and I guess it could have been in a shop without the modern automated equipt.

Maybe the V8 has to sit on the block surface and sleeve go bottom up to take advantage of the flat block surface when lining up for the boring.
