Aluminum block needs sleeved to gain any bore size.

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
Plus they aren't having the same old problems with dropped sleeves like the used to have. Seems to be a legit alternative for more cubes than going with an iron block these days
weight is the main reason why i got this block but as far as big cubes its cheaper to make an ironblock big cubes. i can get 6.0 cores for 3-500 bucks.Originally Posted by Mang213
Of course iron blocks are cheaper, but that wasn't my point. 7-8 years ago, getting an aluminum block sleeved was a shot in the dark for reliability, with bad coolant leaks from the dropped sleeves. Now, with the new sleeving processes that are utilized, a large cube aluminum LS is an option. Big cubes, light weight= win win
And probably still cheaper than an LS7 or C5R block
If weight is all you were worried about you didnt get much difference. 60lbs I think.

actually there are a good bit differences in weight. alum 6.0 to iron 6.0 is around 90lbs, other blocks like the iron 4.8.5.3 have slightly more weight then the 6 litre blocks, of course the lsx is another 35lbs heavier then the standard production blocks
