Sorry about that I thought I had the Motor size in the title.
It's a 460.

The diagram above is just for the emissions devices.
You also have your A/C system and maybe speed Control that is not shown on the above diagram.
Just saying you have two vacuum lines and you do not know where they go does not help me much.

well the two i am having trouble with are,
there is a pink line that looks to me that runs over to the canisters with the red and black ones, not real sure.
there is a bigger line in the back of the intake that has good vacuum, i had a bolt in it and it still runs, but when i take the bolt out it will make it idle faster. i already have one going to the pcv valve.
where does the ac go too.
also there is another pink line that a y and loops back into itself. are there anyother lines that hook into the air box
