![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
Based on the locked thread in the kill forum https://ls1tech.com/forums/street-ra...ck-ls1-43.html post #148, someone stated that there were several 2002 (possibly 2001) Z28's that were released with LS6 blocks!? I know all about my LS6 instake but what's up with the block? I have never, ever heard of this.
Is this confirmed?

There was some word back in the day, (2005-2006) that when the F-body was in its last year of production, they ran short on LS1 blocks so random cars from 2001 and almost all 2002 models came with LS6 blocks. Unfortunately, that was about the extent of it. Aside from improved oil flow passages, not much was deemed to be an improvement over the LS1 counterpart in stock form, and it's not a clear indication of random, 330+RWHP factory freaks running around.

I've only heard that some late production 2002 models came with them.
You can check the part numbers on them, but I believe they're hard to get to. I've seen some selling on eBay with confirmed LS6 blocks. I really don't think it makes much of an improvement, however...

i believe the part number in on the back of the block. i remember guys saying you needed a flash light and a small mirror to be able to read it, thus determining whether its an ls6 block.

This is old news, those of us that have been in this community for a long time have known about this for years.
It's not a big deal at all. The LS6 block offers nothing in terms of HP gains.

An Ls6 block does nothing in terms of performance. All it does is have different style/size oil ports/ducts/tunnels.

As I recall from the umteen threads here about the subject, it was more like 25% of 2002's got the LS6 block.

Here is the relevant information, from JRP's FAQ sticky in the newbie tech section;

Looks like it was about 15% of 2001 and 25% of 2002's that got them.

Yeah, I have been here since 01 but I don't live for this forum as does others.
I've had an 87, 94, 99 & the 02 and no, I did not hear of this as a matter of fact. I left off when there was speculation that LS6 motors were possibly installed in 2002 (the entire motor, not just intake or heads or blocks.)

There was never speculation of entire LS6 long blocks being installed in F-bodies stock, unless you just happened across some joker trying to start rumors.
