The LS6 heads & cam are the big reason for higher HP from the LS6 as opposed to more ventilation providing the HP difference. 15% of '01 fbods and 25% of fbods received the LS6 block.

Not all of the 2002 fbodies had the LS6 block.

I have one

Here are some tell tale signs. Look on the top of the block behind the water pump kin of underneath the TB on the passenger side. If you see a bullseye casting mark, you have an ls1. I you have none, you have an LS6. If you can look on the back of the block underneath the rear drivers side head and see the last four digits of 1168, you definately have an LS6

I cant remember what magazine it was but I do remember it said the later 01 and all 02 but oh well

01 - 02 some got the LS6 blocks and blocks only because they temporarily shut down the LS1 block casting plants in Canada so a few got the LS6

**whiteLS1TA** · 08-19-2007, 08:01 PM

dont the 2001-2002's have ls6 intakes?

**Redphoenix1998** · 08-19-2007, 08:09 PM

all 01-02 came with a LS6 manifold...a low percentage of 01's have the LS6 block and i've heard around 25% of 02's have the LS6 block. I don't think anyone knows the exact figures...

I spent some time today to find out which block I have, and I don't see the bullseye casting. On the other hand I am having a hard time seeing the block underneath the rear drivers side head. All I see is exhaust manifold. Is the serial underneath the exhaust manifold? Anybody managed to take a photo?

It's right behind the head, kinda like a little lip. my blocks on a stand with no heads I could take a pic if that help?

**VTR99** · 08-22-2007, 05:30 PM

By behind the head you mean the back of the block? Seems like it would be nearly impossible to see it next to the firewall.

i know a buddy of mine that has a 2002 WS6 and he has the ls6 block and intake. apparently they ran out of the ls1s closer to the end of the production of fbodies so they used the ls6 blocks to finish the last cars.

all stock 312rwhp and 325ftq

**xirxious** · 08-26-2007, 01:24 AM

Is the Ls6 block a straight swap out for the ls1?

**TripleBlackTA** · 08-26-2007, 07:37 AM

but i thought they all had ls1's and the older ones had lt1's, i didnt think it even went up to 7, unless its not talking about engine or w/e im not sure can some explain to me???

**badazta** · 08-26-2007, 07:44 AM

yes the ls6 block is a direct swap.
