Mystery 6.0 block I'm not even joking, never seen a 6.0 block like this before.
We get core blocks in from a supplier. They can be from anything, I've even received LY6 6.0 iron blocks, long as they're iron LS block he drops them off to me.
Any ideas? i'm thinking its a marine app. block? Forklift application?
The block measures correctly for 6.0, mystery block has fine thread main bolts.
Water jackets are slightly different. It uses long head bolts.
block on left is mystery block,
The Mystery block also had one of these for the timing chain

Call me crazy but could that be a marine engine block? I know alot of the older marine engines had bosses without drilled and tapped holes for accessories and other things. That's really wierd though
looks a lot like this block, but it doesnt have the 6 mount holes on this one.

I noticed the webbing @ the front on the passenger side (#2) is larger . What's the casting # ? Can you get a pic of the back of the block @ #8 where the ? marking is ? This has to be either a marine or possible industrial app .

I'd like to think its a marine block, I don't understand why the marine block wouldn't be listed in ie GMPP catalog, GM only builds parts for internal use, I couldn't image them giving .02 for designing a block entirely for marine use, i'd figure the factory 6.0 would suit the marine market.
One person suggested this block could be from Isuzu and/or Kodiak trucks.

I wouldnt be surprised if it was from one of those trucks. from what ive seen they do use similar ls parts but with the slightest differances.. those ls eng are the one that geat beat hard! FYI they were using the cast 2001-2002 f-body exhaust manifolds but with out any of the air or egr drilled. and yet they run so hard they crack these manifolds which ive yet to see an f-body crack one
That looks like the early LS series of blocks. That tensioner for the timing chain was on the original pre production blocks also and was deleted before production. The venting holes were not in the original block until they did in car testing and realized the problems with windage in the skirted block. Looks like a pre production block from 1995 or 96. I had never seen a cast iron one......

pre production would make sence because it is iron and if , i remember correctly the pre productions were iron and i have a LQ4 sitting in my garage right next to an LS1 out of a 2000 vette and there is 6 mounting holes on one side and 5 on the other so it was probably casted in the original LS1 mold before the aluminum blocks , Eric
