IS There advantages in having a ls6 block instead of the ls1 block????? I think i might have a ls6 block in my 02 T/A.i know they come with the ls6 intake,however G.M. supposedly around the middle of 01 putting in ls6 blocks instead of the reg.ls1.I'M trying to find out for sure if i do or dont, but was wondering if there was any "bennies" if i did?? anyone know???

as i suspected, according to soggy dickey performance parts, they list LS1/LS6 blocks as same part #

 

i dont understand why, because from that manufacturing article, clearly shows they are diff.

 

whoah.......... heck of alot of info there....
THANKS MUCH ... IVE COPIED AND PRINTED IT SO NOW I'VE GOT SOME LOOKING TO DO. THANKS AGAIN FOR THE INFO AND QUICK REPLYS.........

 

From all the resaerch and hands on Ive done... I have only seen 1 '02 with a different style block. It was made late in the 02 year (near the end) It is a different casting that the previous.. Id say 20... that Ive personally looked at (01 and 02). All the ones Ive seen are the typical LS1 block. Its silver and has kind of a shine to it. The newer casting is a grey casting and doesnt have the "bullseye" markings in the other thread I had that was posted earlier. It may have been a LS6 block. I havent personally seen one myself yet.

There is no performance advantages of the LS6 block. The later 01 and 02 LS1 blocks incoperate the same features such as the breather hole in the top of the crank journals to help with the oil. They list the same part number for both blocks because they can only get what GM is having produced that year and you can use either for the same application. It doesnt matter.

Hope this helps out some <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

THANKS for the picture. yep.... i've got the notch in my 02 WS6 just like the picture. IT has an AUG.01 build date. as far as the color, guess i'm just going to have to look at another one,like an 2000,or 99. Thanks much, Terry.

 

That isnt the right notch... All the LS1 blocks Ive seen have that same notch, look at the color of the block. Its grey and has a sandy finish and doesnt have the bullseye marking below the "notch".

The LS1 blocks are about the same color as the ideler pulley/tensioner in the picture above. Notice the difference in the 2 colors <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

OK THEN, COUNTRY BOY, I'M looking for a grey,sandy type finish / and color, and NO bullseye anyplace, right??? if right color, and finish and NO bullseye then i could have an LS6 Block.....Right????? thanks...Terry.

 

Country Boy please look here and tell me which is the notch that everyone is refering to to tell if it is a LS6 or LS1

i know my block is the right color and texture i just want to make sure thanks

The top circle is the notch people refer to. Ive seen that same "notch" on all the blocks Ive seen so far. I havent seen a LS6 block up close yet to see what they have in that place (the top circle)

The bottom circle on the ledge is where the bullseye would be if it was the old LS1 casting. Ill take a pic of my block in a few and post it for you to compare <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

thanks alot Carl <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Heres the pic to hopefully help some better if they are confused. Compare it to your block. This is a older style LS1 block I have no pics of the LS6 block to say for sure if they are the same. I wish someone could post one up of the same shot here!!!
