Has anyone resleaved a iron block?

Umm from what I gather, an iron block doesnt have sleeves.
You can get 427CI from an iron block by going to a 4.06 bore and using a 4.125 crank.
Most engine builders dont like to go much over the 4.03 bore though especially if you are gonna be using nitrous.

werd, iron blocks don't have sleeves man. You just bore them, and to tell you the truth I wouldn't take it over .030 over (4.03), that's just me tho. If you take it .060 over then you the block can't be reused if you ever scar a cylinder. The extra cubic inches from boring it .060 is not worth the HP gain in my book unless you poop $100 bills and can afford to replace the block whenever needed (not saying you would ever have to) then go for it lol. But ya, aluminum blocks have iron sleeves because if they didn't the piston would wear and tear an aluminum cylinder faster than you can think also do to the expansion rate of aluminum as well.

Actually, you can sleeve an iron block, but Ive only seen it done to stock bore size. Its an actual replacement cylinder if one should crack, but I havent seen them hold up too well.
If its the same structure as the aluminum block. You may be able to use the Darton setups.

I think I would have just bought a Lambo
I especially like this part:
Isky gold springs

isnt going to darton sleeves strong enough? why put them into a cast iron block. i would say this would be over kill. also considering that it would cost about the same to do a iron block as doing a LS1 block, i would rather get the weight saveings that the LS1 block would give me.

Sleevin' an iron block is no sweat, seen it done almost on a weekly basis. The main thing is to be sure that there is enough material left after boring it to the sleeve size to support it good. Most top end shops machine the block to about .003" undersize for an interferance fit to the O.D. of the sleeve and put the sleeve in dry ice to freeze shrink it and hand install the sleeve. Other shops just drive 'em in w/ a air hammer. Either way works fine as long as they leave a step at the bottom of the block so the sleeve cannot move down after time. I think on some blocks with core shift cutting .175" out of the cylinder will hit water jacket too much to properly support the sleeve. The main thing I would do is have the block sonic checked for thickness first.

MID sleeved iron block
I finished machining and installing MID sleeves into an iron block yesterday. It takes a lot longer to machine the iron block than an aluminum one - more $$$$$$$$$$. A lot harder on tooling and my back as well.
In any case, except for a very minor break through at the front of the block which I sealed (iron block core is different from the aluminum blocks) the assembly went very well.
The MID sleeves are longer than the original bore in the iron block by about an eight inch. This should help support the pistons better with stroker cranks.
I have yet to deck this block but the photo shows the sleeves installed.
