Hi. Can anyone tell me for sure if a 1982 ford bronco with stock elctronic ignition, had timed or ported vaccume. Or did it use manifold vaccume for the vac advance on the distributer. I was kind of thinking all older fords used ported vaccume, but im not sure, and its not really running quite right either way. I would like to know for sure so I can eliminate this potential problem and move on. I rebuilt this engine, high performance and stuck it in a 1971 F250 4X4 crewcab. I have no idea where the vac hoses in the bronco went.
Thank You

It woud depend on the engine and wether carbed or injected.

I don't want to give em a heart-attack. That is what would happen if I answered the door in the buff. Heck it almost scares me to death when I step out of the shower and look in the mirror.~Mancar1~

Re: ported vaccume?
It's got two ports, no. The one on the end makes it advance. Theres a hole where the hose goes on. Inside, theres
a 1/8" allen nut. More later.
In the 80's Ford had 20 or 30 different vac. diagrams for each car/truck. This was a royal PITA. I used to "smog test"
a lot of these POS's. Cut to the chase. Ported vac to the end hookup on the dist vac advance. The other port is vac.
retard. I would not use that. For "NOX" reduction. Who cares about "Nox"! It's all BS anyway, Like the R12 thing.
Jeez, do you have to smog test it? If not we can make it work pretty easy. Jake
The 1/8" allen screw adjusts the spring in the vac. can on the distributor. The allen goes in the vac. port.
Trial & error. Turn it to far left and it will fall apart. Two turns either way is usually safe. Keep track if you
do it. Jake

Re: ported vaccume?
Sorry I thought I put the engine in there. Its a 300 six, carburated, and there is only one vac hose conection on the end of vac cylinder on the distributer.
The 82 had smog, this was put in a 71 and built to 71 specs, except I upgraded to the electronic ignition out of the 82. It does not need to be tested.
Thanks

Re: ported vaccume?
Ok. THANK YOU! I already went, and im going to stay ported. Timing is perfect, no fuel leaks, fuel psi perfect, plugs fine,ect,ect,ect,ect, ......
I found a possable problem and now I am not sure what im going to do.
The correct awnser to the question I posted here is : None of the above!
The 82 had an air pump and emission controlls. The vacumme ran thru an emission controll valve and used a blend of both timed and manifold vacumme acording to that valve.
I bought an 82 distributer to match the 82 electronic ignition I used.,but this engine does not have those controlls. Now I think both the vacume and mechanical advance curves may be wrong because of this.
Im not sure what to do know. I dont have the money for another new distributer, and I dont have the skill or equipment to build a new advance curve.
Thanks Mike
