Default LS1 or LS6 intake?
Gotten different answers... now I leave it to the mob -

At this point I'm still even confused as to if I have a LS1 intake or LS6 .. I do have a tube running ot the side of the throttle body... wrapped in some rubber membrane.

i see that you have an 01 ss?

should come factory with a ls6 intake. did u buy the car modded? best thing to do is get the serial number off the side of the intake.

thats an ls6 intake. do you see rite behind the throttle body on the top of the intake at the front there is a diamond(square shape) on the nose of the intake? there should be a tube running into it which is the EGR. Yours doesnt so its an ls6 intake. 2001 and 02's have an ls6 intake.

This is just my observation, but! I would say that your motor was changed at some point because it does looks like its an LS6 intake but you have the old style PCV which is the black hose there on the left side of your picture. I though on the motors that came with the LS6 intake had the different valley pan cover where the PCV hose comes out the front of the cover and plugged into that side port of the intake. Its just weird.

The only way to know for sure if it's an LS6 intake manifold
is to run the part number or pull the intake & see if the bottom
is flat. The part number is on the drivers side.

Some LS1 corvette intakes didn't have the EGR.

Well this is the big puzzle, and I will give a piece of it. I got this through a dealership in Colorado before I moved back up Northeast. I asked for a carfax when I first started the process, towards the middle ... slipped my mind. Of course shortly after taking it home I realized from obvious signs, he car was in an accident. I've been looking for someone who has an open carfax 30 day or lifetime account. Its to the point I know it was damaged .. and restored. It would be great if someone had a carfax account ... .

I knew about the tube .. and I see the plug in the throttle body, but I just wasn't sure.

it SHOULD be an ls6, just run the part number. Also, what heads do you have, 853 or 241?

No idea what heads I have. Havent gotten that far with the car yet. As is I, just a few days ago, finally got a good price on the passenger low beam light. Paid 40 for a brand new one. Heads arent my league ... working up there though.

underneath, the intakes are clearly different. the ls1 intake has a curved floor and the ls6 has a flat floor, which is why you would need a particular steam line for each of them!

No, not so.

only the LS6 Y-car got the LS6 valley plate.

his picture shows the standard 1999+ F-car PCV system and the 2001+ F-car intake manifold (i.e. LS6 intake, part number 12561184).

Op: go look on the LHS of your intake, you will see the part number molded in the plastic.
