Well, It could go there, but the factory connection for the trans was the rear manifold fitting. That carb fitting is very convenient for connecting the manifold vacuum part of the Distributor Vacuum Control circuit, but again, since the 4160 was not a factory installation, Ford connected it elsewhere.
For example, the "red stripe" hose could be connected to that port-

I answered a 6 year old thread??? I was looking for a Holley carb. part and I guess that question popped up. Stupid computers! I changed my 289 for a 302 with aftermarket intake manifold and Carb, so that is where I had to connect my trans vacuum......didn't know it was a 6 year old thread and don't even know how I ended up on Mustang Forms.
For whats its worth there is somewhat of debate between running a vac advance dizzy off of full manifold vac OR ported vac.
distributor manufactures will always tell you to run ported vac.
However there is a following of individuals that have good success running full manifold vac on there distributors.
I have tried both and I found that running full manifold vac caused the exhaust to smell rich and unburned despite allowing me to run idle mix a full air fuel ratio point higher than I could with ported vac. Im thinking this is due to reduced exhaust gas temps in the headers not fully burning off the exhaust.
