i asked about this a while back but didnt really get much of an answer. this is one of the last steps before i finally get to start the engine and i need to know now. i am trying to connect all my vaume lines up but am not sure where they go. i have a vacume advance dist. with dual ports, a 3-way pvs valve, two on the edelbrock carb (but only the non-emmision controlled port will be used) and one on the intake. i have looked through several diagrams but they are all mentioning an "electronic control module" or something like that. i do not have this module and DONT THINK i need it because my car does not need to be smogged. any help on where each hose should go would be appreciated. thanks.

I have the Osborn's Chassis manual for '68 which shows a range of options for hose routings, depending on engine, smogging, carb, etc.
I'm not saying I can answer all your questions. But we do need to know your engine and year. And also, as far as I know, nothing was written in stone about where the hoses went.
So what have you got? And what particular hoses are without a home?

im a little lost here but i would hook the pvc valves to the intake hole. then hook the vacuum advance line to the carb. then plug everything else and try it!!!------------------

im sorry. i always forget to mention what engine i have when i ask about it!!  i have a 70 2v cleveland. the eddelbrock has two ports. one for emssion controlled engines and one for non-controlled emission engines. so i guess i plug the emission controlled port and use the other. now the instructions for the carb say to hook that port up to the intake. but my manual shows a hose going from that port to the dist. i am pretty confused on all of this. so right now no hoses are hooked up. i really dont know where to start.

I'd be happy to snap a pic of my setup for you and email it to you. Let me know if you are interested. I have a 289 but they all generally hook up the same way.

kewljay, I'm starting to feel for you  Unless someone pitches up with a 70 2V Cleveland, I'm gonna run you through the hoses on a '68 390 2V, which could be very similar.
Here's a bit of unsolicited advice ... I get by far the best results at M&M when I use really specific subject lines. Yours would be something like "Vacuum hoses on 70 2V Cleveland?" Very few folks with those engines can resist taking a look! And if they don't know the answer from the top of their head, they just have to pop the hood.

could you let me know how yours are set up also if possible? then i can compare the two cars and probably get an educated guess on how to do mine. and thanks for the advise. i will use that from now on when i post something new.

OK, here are the max. vacuum routes for a '68 390 2V with automatic transmission and dual diaphragm distributor.
In front of the distributor you have a vacuum junction with three ports (VJ1).
From the front diaphragm of the vac. advance, the hose goes to VJ1. From the rear diaphragm, the hose goes to a tee joint.
One port from VJ1 connects also to that tee joint, and then a hose goes from the tee joint to another vacuum junction at the rear of the manifold (VJ2).
The third port on VJ1 connects to the front of the carb. (The carb is not identified in the drawing I'm using.)
From VJ2, there are all sorts of permutations depending on whether you have AC, power brakes, speed control, a tilt steering wheel, or headlamp windows (Cougar only).
Is this useful so far? I won't be offended if not  If you want me to carry on beyond VJ2, let me know what options you have that need vacuum.[This message has been edited by Fastback68 (edited 10-07-2003).]

yes this is making sense to me. but this junction that you are talking about that is in frot of the distributor, is this the PVS valve? if so, i have it and it is threaded into my water pump. each port is labeled... the port furthest from the threades is labeled "1". the center port is labeled with a "D". and the port closest to the threads is labeled with a "2". you mentioned 3 different hoses that connect to this junction. which hose goes to the "1", "D", and "2"??? i have one port on my intake at this moment. there is one other one but it is plugged. what can i use that for? and finaly on the back of my carb is a port that from what i understand by reading the instructions from edelbrock is that it connects to the brake booster.to make things more confusing, my booster has a junction on it. there are three ports. two are plugged and the other i am guessing is for the back of the carb which i previously mentioned. what do you think the other two ports could be used for? do i even need to use them?

kewljay, I got a chance to go look under the hood of my 70 Torino tha has a 351C in it. The 3 hoses are as follows on my engine Top Port(1) - goes to the rear connector, closest to the distributor cap on the vacuum advance.
Middle Port (D)- goes to a ported vacuum port on the carb.
Bottom Port (2) - goes to the front connector on the vacuum advance.
I have a shaker so the line going to the #2 port has a tee in it going to the air cleaner snorkel servo and the line going to "D" has a tee in it going to the flapper servo on the shaker. If you do not have a shaker. My car also has a "junction" mounted on the firewall that the brake booster hooks to. Mine has 6 ports 2 large and 4 small. 1 large goes to the intake mainfold for the vacuum supply, tha other large port goes to the brake booster. 1 small port goes to the transmission vacuum modulator, 1 goes to the vacuum canistor that feeds all the AC/heating system controls, the other 2 ports are plugged. I would guess that they would be used for other vacuum operate accesories such as hide-away headlights. I hope this make some since to you, I do not have enough light to take a picture that would show anything, plus everything would just look black with the 33 years of crud. ------------------
