Has anyone confirmed that the block used in the 2002's is the same that is used on the LS6? I know my block is different than those in 2000 and newer cars and also think the casting of the heads is different also.

Some 2001 cars (later in the build-year) and all 2002 cars have the LS6 block. I'm not sure how to tell, I'm sure someone here will chime in with what to look for...

From what I've seen on a few 2002 Z06's my block looks externally the same.

i read in a post somewhere that there is some code or marking on the block that supposedly is a z06 block...ive also heard that no z06 blocks went into any f cars... <img src="images/icons/confused.gif" border="0">

I heard (but do not know if it is true) that you can tell by looking for a small bevel in the block on the front passenger side near where the head bolts to the block. The LS6 blocks have this bevel, while the LS1s do not. Once again, I do not know if this is true.

I concur with WeatherGuy. Look for the small routing hole where he described. Actually my car was made in March of 2000 and has it. Big Whooppee, its not like it helps <img src="images/icons/wink.gif" border="0">

Mine does have the machined section on the passenger front side. I guess I'll just have to wait and see if it ever makes any difference that I have this block.

I've also heard that some 2001's had the LS6 block in it..

I didnt know there was a difference between the two blocks..

I thought ALL LS1's are LS6 blocks now as of 2001, along with the intake manifold.
