Found out my SS had sort of a Frankenstein engine last night, lol. Okay, soo I have a 2001 SS...well last year I swapped the motor out with the motor that was in my gf's 99 T/A. Basically, stock for H/C setup (reason I bought her car was for the mods)...anyways her car is at my buddy's house currently getting the headers and LS6 intake swapped out for the stock stuff because she wants a new car (no reason to let the mods go).
Well, my buddy calls me up and is like "hey umm your car has an LS1 engine valley cover, and an LS6 intake manifold...that doesnt make sense" soo we tried to figure it out for a few minutes but counldnt come up with any ideas...then he says "ohh yea your block is the '00 and older...not the newer 01+ style". Then it all made sense to me...
My 01 was an early production car...soo I am guessing at the factory I somehow got the older block and engine valley cover...but still got the LS6 intake manifold. Soo in essence, I got the better manifold, but still the the oil consumption issues!!
Anyways, just thought I'd share...
Way to go GM!!

) than the LS1 block and different materials were used.

Here, check this out......
"Apparently there have always been two version of the LS1: One built in Montupet, and one built in Nemak, Mexico. They use two different methods in creating the block, and apparently the Nemak block is a stronger, more performance oriented block. (The material properties were about 10% higher/stronger. Nemak uses a low-pressure precision fan process, more high performance oriented.). When the Z06 Corvette came out, GM decided to use the Nemak plant to build the LS6 block, since they built stronger blocks. So Nemak built LS6's, while Montupet built LS1's. Since there were so many LS6 blocks made, several made it into F-bodies. Numbers from GM are that about 10-15% of 2001 cars had LS6 blocks, and 25% of 2002 cars did. To confirm if your 2001-2002 F-body has an LS6 block, grab a mirror and a flashlight. Open the hood and head over to the driver's side to try and see the back of the left-hand deck, above the transmission flange. A cast-in #12561168 denotes the LS6 block. And if you aren't able to see the number, you may be able to tell by the block's luster-the Montupet plant cast a shinier block, the Nemak plant made the duller block. The Z06 block (LS6 block) is not only much stronger, it also has 87% better ventilation between bays, which equates to less pumping losses at high RPM's. I have not had the opportunity yet to determine which block is in my car."
Ls6 blocks were manufactured in nemak, Mexico like Unit said.
