anyone know?

 

I found this in an article that came up when i googled lsx block weight...

"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"

 

I dont seem to think that the ls1 block is 100 pounds though I have not weighed mine but I pick it up and move it around like it is nothing. that or im the incredible hulk. lol.

 

I think it's about 60-80lbs or so. The LSX block is heavy.

 

The LSX block is incredibly dense also. I was reading GMHTP and they said the block is near the point of being unable to work with (boring/honing) because of its tensile strength.

 

I saw a similar thing where they said they could have made it even denser / stronger but it would be difficult for the average machine shop to work on.

 

i agree...the lsx is a great block, but the weight is one of the things holding it back...very strong though

 

I heard the LQ4 is 70-90 pounds heavier than the LS1... not sure about the LSX

 

alum block ~110lbs
iron block ~175lbs
lsx block ~225lbs
