Quadrajet Vacuum Ports ??
Just received my new quadrajet.
it's model 7043250 which i'm told is 1973 and from a 350 ??
Before I attempt the job, can anyone please indicate what the ports are and what goes where? I took photo's but haven't got a USB cable to hand so have numbered the ports in question on this diagram i found on google.
I'm guessing number 2 is for EG valve ??
There are also 2 ports at the rear of the carb near the top, one is bigger than the other (6 and 7, with 6 being largest).

#1 i believe goes to the pull off right above it.
#2 PCV on valve cover
#3 probably go to the vacuum switch in the water port on the front of the intake manifold.
#4 distributor vacuum advance
#5 is a vent that you don't mess with
#6 and #7 are just for filtered air and have no vacuum on them. one will go to the choke thermostat. the other will probably go to a vacuum switch that screws into the water port on the front of the intake manifold.
i am no expert but think this is correct. i am sure that someone else will correct me if i am wrong.

great thanks.
not sure about number 1 as there is already a hose connecting the diaphragm to a port??
i currently have an edelbrock performer intake with edelbrock carb and when i set that up all i had was a vacuum line from the trans and one from the distributor. Where would i put the transmission?
and if the others are unused, should i simply block them off?
