How to identify a LS6 intake?

***SMWS6TA*** · 08-31-2010, 05:53 AM

Quick question. Tomorrow I'm meeting a guy to buy his LS6 intake and I want to know how can I tell if an intake is a LS6 intake and not a LS1?

Any specific part # or something that lets you know it's a LS6 intake. Pic would help

Thx ahead of time

the ls6 intake manifold will have a rounded bottom instead of a flat one like the ls1. there will also be no egr provision on the neck of the ls6 like it is on the ls1.

also there will be a number stamped onto the side of the intake...here are the numbers

Stock 2001-2002 F-body LS6 is 12561184.

The Z06 LS6 is 12573572.

The old LS1 intake with the EGR setup is 12560688.

97-00 vette LS1 part # is 12556333

dang shady....you have that backwards. The LS6 intake has a flat bottom

Reading in that ling I saw that I need to shave the bottom so that it will fit on my 98? Also the link on how to install seems to have expired. Any body have some more directions?

Got the intake, Ported TB and as a bonus He also threw in ARP bolts for it, just ordered the LS6 Coolant kit. Now I need instructions on what the hell I need to do....
