i have a 2008 Chevy silverado with a 6.0 liter V8. It has an aluminum block. Does anyone know if it will hold up over time or will it crack over time? I have never heard of an aluminum motor before. Didn't know if I should get rid of it before it gains too many miles or if I should keep it if it's able to hold up for years to come.
you have a LSx block unless you plan on making in excess of 650HP-700HP the lsx block should hold up just fine.
the aluminum block GM motors came out in 97 on the C5 corvette and have been solid ever since. Even the 505HP Z06 corvette is based on the LSx block just punched out to 7.0 liters
here is tons of info on the LSx block: http://www.hotrod.com/howto/113_0504...ics/index.html
aluminum has been used as a block material for decades with mix results in the early years. for instance the ZR1 corvettes use an all aluminum 427 chevy big block to great effect, but it was quite expensive and thus not many were made. the chevy vega on the other hand used an aluminum engine that was a poor overall design. while the blocks had no issues, the open deck design and a lack of steel cylinder liners meant that the engine had several problems through out its entire run. ford has used aluminum as a block material since 1992 when they put the 4.6 mod motor in the lincoln, and later they switched all the mod motor blocks to aluminum, again to great effect. the current lsx engines are quite good, and as stated if you are not going to make big power, they should last a long time.
Aluminum block engines are in Volvos and they run hundreds of thousands of miles without issue. I believe they use steel or some other metal as a sleeve material in the cylinders. Also I agree with the above poster, if it overheats you have to treat it carefully. They can survive a little overheating incident but not too much or the block itself will warp.

the LSX block is not the production line engine block. It is strictly the higher hp 'vette and over the counter only block. I have 2 of those over rated LS things on engine stands now.

yes it is LSx just means it it is from the GM LS engine family. it could be Gen III LS1 5.7 also in the Gen III family are the vortec 4.8 and voertec 5.3 and vortec 6.0 they were around from 1997-2007 in GM cars and trucks
then you have the gen IV LS series which came out in 2005 with the LS2/LS3
and again the
gen IV 4.8 vortec
gen IV 5.3 vortec
6.0 LS2
6.2 LS3
7.0 LS7
the LSx is not overrated they are huge with aftermarket tuners and old school hot rodders
My BMW has an aluminum block V8, and it has 180k miles on it. Most modern engines are aluminum, or at least have aluminum heads. Sometimes you'll still see cast iron for the block in a supercharged or turbocharged engine, but even that's going away.

As far as I know all LS truck engines are iron block and aluminum heads. And they hold up very well.
