What year is that Z. It looks like a 75 by the fise box and intake manifold. The intake is different on mine.

 

Built Jan 1977
5sp
AC

 

I mean mine, don't know about the pic, but it is FI

 

Well wofl66 I ahve taken the picture out to the garage and capmared it to my Z. If you look at the back of the intake towards the windshield. You will see that the canister and the air regulator are gone. This is possible with headers. But this car ahs none. It still has the stock exhaust. And the rest of the can be removed if you put in a new fuel rail and take out the fuel charcoal canister. This Z doesnt have any kind of choke, or fast idle. With you living in Fl you can get away with this. With me living in Idaho where it is 18 degrees outside I need them.
Well I hope this has helped
