W/r/t "Get the thickest sleeve you can"
Because you know exactly how thick the walls are in each direction of all 8 cylinders.
Where can I look this up?

Where can I look this up? I guess I need to type out WITHIN REASON. It’s called using your head. Every sleeve EVER is under nominal by at least .030 so IF you chose a nominally sized sleeve that is thin and you bore most of it out to get to size what did you gain? Have you ever set a sleeve? Just one? If so, you’d understand this.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Think you mean 4.532. What bore are they ? Not sure what you mean by ‘they’ but those sleeves are out a older fuel block are 4.70 top and 4.63 at bottom, 4.31 inside. My block bore is 4.530 so if turn them to 4.529, heat the block, chill the sleeve they should drop in. I’ll cut the lip down then make a cutter to cut top of block to accept that lip so it will not move (which I doubt). I think those sleeves are some good material to support a fuel engine. KB sleeves if I remember right. I had vagly thought of using them but after reading the posts they might be the best option plus they where free.

The sleeve's OD needs to be larger than the bore diameter so there's a press fit. I'd still bore the block out slightly to get the step at the bottom for the sleeve to sit on.

Lol They, those, them Kinda like the 3 who’s Who knows, who cares and who gives a [censored] I’m sure you know you really should start with a fresh bore but If you turn them to fit the 4.53 “they” will still be .110 wall

You need a step or a flange in my opinion, and you need to be .001 to .0015 over the bore dia. You maynot need a step or flange at .003 or better.

Probably an old mega block,
at 4.53 I’d be looking for the cheapest way out also
instead of spending $1900 on pistons Ditto

Also after getting more of the picture, With sound bores and flanged sleeves you could be at .0005 to .001 for this.
What is the condition of the bores? Finished honed and straight? Yes good finish and straight, my concern when looking for pistons from the big engine builders, they said they never go over standard (4.5) because when bored there’s not enough material left between the cylinders = blown head gasket. I guess they made throw away blocks. Then the other can of worms is if all 8 holes are sleeved how weak-thin will cylinders be then (Siamese block) I feel like I’m in no mans land. I have everything there for this engine waiting now in limbo. One other thought, can standard pistons be coated .030?

Diamond made me a set of 4.510" hemi pistons and they were over $1700 two years ago.

maybe try a different brand. I agree, I was just saying I don't think he's too far off w/ his $1900 estimate. I'd still rather run the block at 4.530" bore than put 8 sleeves in it.

Just for kicks I went to JE site and looked BB Chevy pistons, !! 4.53 1.52 ch .990 pin $91.00 ?!! Now that flat top only give me 8-1 compression.. but.. I would do in a street engine on pump gas. $730 instead of the $1900 quoted. lol
