I'm currently working out a good deal on a new Edelbrock intake manifold, because I believe there are some severe vac leaks, and instead of taking the manifold off and looking it all over, I'd rather just replace it while it's out, hopefully fix the problems, and take the performance increase

I took a bunch of pics, in hopes of catching all of the angles, to make it easier for you all to identify everything:

First off we have this thing here.. before I took the QJet off, it was hooked up to the carb, to the upper left of the fuel line if you're facing the front of the car. I'm not sure where to hook this up, currently it's on Full Manifold Vac next to the PCV port on the front of the Holley, but I'm not sure if this is correct.




This next pic is of the above thing, and a hose that runs from something beneath the intake manifold to a port on the intake manifold (this is to the left of the thing in the previous pics)


Next up is a metal line that I believe runs to the transmission, then goes into a rubber vac line that used to be hooked up to a port towards the bottom left of the QJet (if you're facing the car). I read on the web that this has to do with upshifting the auto tranny.. just wanted to confirm that (or tell me that's totally wrong).. also I'm not sure where to hook this up, I currently have it on the vac T that goes to the other accesories (power brakes, etc.)



Then there's this thing which was never hooked up to anything, and I wasn't even going to bring up, until I noticed it said "EGR" and "CARB" so I started thinking it was supposed to be hooked up to something.


Lastly there's this UFO shaped thing, which I was told is the EGR valve, so I just wanted to confirm that (or not!). It used to have a place on the QJet, but I was told I could just plug it, so when I installed the Holley, I did just that.


And that's it! Here's a few pics of the engine bay, incase it's hard for youg guys to figure out what anything is from the close-ups, this should give you a better idea of where everything is positioned overall.




Sorry for all of the pics, but I just want to make sure I understand everything before I start taking things apart! Thanks guys!

First Pic. No problem you can just block it off completely at the carb cuz it's doing squat now anyway.
Second Pic. If I'm reading it right, your talking about your PCV valve. Looks good to go.
Third Pic. That is the vacuum line to your modulator and does regulate trans shifting.
Forth pic. Not anything that is needed unless you have your EGR system hooked up, which you don't.
Fifth Pic. As stated, that is your EGR valve.

Everything is as it should be.
