I have a 1977 T/A with a new build on a 400. I need help hooking up the vaccume lines on the carb. It is 1975 quadrajet. If anyone could tell me what goes to what or even have some pics that would be great.

If you have a Chiltons manual for your car, it will show where all the lines for you make/model should go. The rest of the vacuum ports can be plugged. Also, a google search might show you where they go. It varys from make/model/year so it's hard to determine exactly where by your description.
My 71 has 5 major hook ups for vacuum lines.
1. from the heater/A/C control
2. from the distributor
3. from the vacuum assisted brake booster
4. the PCV valve
5. The gas tank recirculation canister
1-3 I have hooked up to the back below the throttle butterfiles to see vacuum all the time
4 and 5 I have hooked up to the front before the butterflies to see vacuum when ever I apply throttle.  
Jim,

Ok thanks. I think the vacuum ports on my carb are set up a little different than yours but I think as long as they are all getting a vacuum from somewhere it should be fine.

one more thing...   look around on your car.. there should be a vacuum diagram pasted somewhere ... radiator core support.. fan shroud..  air cleaner.. inner fender wells...   probably not on a valve cover..

take a good picture of it...    post it to one of the photo post web sites... post the link....

post the pictures of your engine also... and 5 views or more of the carb...   do you still have the 77 carb???

there might be differences..
post carb numbers...     stamped in the right side of the main body..    170????? the second row also.. that gives the date code...

and.. does your car have to pass a smog inspection.. visual and sniffer test????

Thanks, That should help a lot. Ill take a look at those diagrams. I pretty much had to buy almost all new parts for this car so most of the parts you listed that would have a diagram on them did not come with the car when in bought it. All that i have is the one carb and I think its a 74-75 model. Ill take a picture of the carb and engine. Also, no smog inspection needed.
