sleeving any alumn. LS block is a big ball O wax, you are correct if low cost is your issue stay away from sleeves on the LS series.

The approx. cost depending on your location would run any were from $150-$200 for one stock type replacement sleeve installed... all they are basically doing is over boring the block past the OEM sleeve to install a new thicker sleeve. Then finishing it to size.

BTW when done properly a sleeve is Just as strong if not stronger then the one it replaced... There is a reason why Pro mod engines use a similar design on there blocks...

The block can be repaired for a bit under $600. I don't think it is worth it.

The cracked cast in sleeve is machined out. Then the cracked block cylinder wall is welded up and the block is stress relieved. Then the bore is machined to accept a custom made sleeve which I machine from a Darton liner for another application.

I repair quite a few LS7 blocks using the above technique. I modify an LS7 Darton 4.125" dry liner to fit the LS7 block. Since the LS7 block is a more expensive piece to begin with, the repair makes more sense.

Cost of MID is considerably more than $1,800 by the way. Your block would be a good candidate if you were building a high horsepower engine.

why would you sleeve an iron 6.0 ? and i am pretty sure the iron blocks do not have sleeves from factory.

Please keep in mind the original question in this topic was to install one sleeve as a repair. Its done for a repair if your cylinder is damaged. Like if you have a crack, a deep grove, or pitting from rust. A replacement sleeve is the cheap part. Its usually the labor that adds up. They must over bore the cylinder, machine the very bottom of the cylinder to locate the new sleeve, install the sleeve, deck the top of the block and then machine that sleeve to the proper bore demension. It can be time consuming. If its not done properly the sleeve will either rotate or can become dislodged causing major damage...

This process of installing 1 sleeve as a repair is usually done to save a hard to find block or if you have a numbers maching block for a restoration. It's also very common for aluminum blocks.

crack in the #1. leaking headgasket, locked up that cylinder.

this was a repair, as the iron blocks do not have sleeves from the factory.

^^^ you left out that the cylinder bore has to be honed.

No, actually I did not. I said it had to be "machined" to its "final" demension. That would include Boring and or Honing to achieve its "final deminsion".
