i think he means, durable, yes it is durable and this was the only way of doing this i believe until the LSx block was out.

the cylinders will actually be stronger

Sleeved blocks vs the cast iron blocks. Its always more money for aluminum over cast iron, and weight is MUCH lighter for aluminum.
The Darton jugs in those pics (like the ones in my car since 04') are used alot for imports to achieve crap-tons of boost. These jugs, if installed right, are monsters.
Peace,

One of the things that makes the LSX so tough is the sheer amount of cast iron that goes into it, causing the standard deck version to weigh in at a full 225 lbs. With the weight of your average LS1 or LS2 aluminum block being about half this--and a production iron block falling somewhere in between--a vehicle with an LSX Bowtie Block will incur somewhat of a weight penalty. But this extra mass is thanks to the GMPP team having added extra material in several critical areas, including around the cam tunnel, around all of the bores, under the deck surface, and about the head bolt holes. Mr. Bates explains why this is and how it relates to Warren Johnson. "We're trying to accommodate everyone with this block, and if it wasn't for trying to make it economical to cast in any kind of volume, then sure, there are places where meat could have been taken out. But we had to evaluate: is it better to have an extra 5 or 10 lbs, or to make the block $700 more expensive to the consumer? The good news is that those that want to lighten the block for their application can hook up with their CNC house of choice and take an extra 20, 30, or even 40 lbs out of it. And as far as WJ goes, we're looking at what potentially would be considered a Warren Johnson special edition of this block that has a whole bunch of weight knocked out of it from the get-go."
I think after the bore from 3.95 to 4.125 and all the machine work, my LSX weighed in around 200 lbs.
Which in turn is around 80lbs heavier than going with another re-sleeved ls2 block.
I felt that I could deal with the weight.
Nice pictures too btw!

Verdad Gallardo I had some sleeves fall on my last block.
They were not like the ones shown though.
They were the one's MTI was using before they started using the Darton sleeves.

It is a steel sleeve and the block will grow faster than the expansion of the steel sleeve.
The last poster had a "dry" sleeve and they were MORE apt to fail/drop. (From the machining purposes as well.)
from what I learned when I looked into it your looking at @ $950-1300 for the sleeves alone and then you need them installed so: $200 for LS1 block + $950-1300 for sleeves, then machine work $800-1100= @ 1800-2200 for the block alone.
Not cheap at all and then you run the risk of the sleeves failing

MTI sells their wet sleeved ls2's for $3,600 or $2,600 exchange!!!
