If there is no EGR and no provision for it, it is most likley a LS-6.

Flip it over, is the bottom of it flat or wavy?

If flat, LS6
If wavy, LS1

Corvette ls1 intakes also have no EGR. Just be careful if you are purchasing it. Make sure it has the brass inserts for the throttle cable bracket to bolt to. Corvette's didn't have that (Fly by wire) so if those are there and the bottom is flat then LS6.

It's an LS1. Here's a list I compiled last year.

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

I believe that the F-body manifold is preferred and flows a little better than the Z06.

Either that or the person who used to own the car bought the intake and tried to hook the EGR back up. Obviouslly it didn't work to well so he plugged it. That is about the worst block off job I have ever seen. I'd ditch that thing and buy one that has not been tampered with.

If not, take that crap out and clean it up, and get a expanding plug for it. Save you some money, just make sure you clean it up REAL WELL. That kind looks like ****(plug job).
