F100 Conversion

I bought a 1982 Ford F100 a while back, and I had the bright idea to rebuild the carburetor as my first project. It was a 2 barrel Variable Venturi, and I messed it up somehow. Now I bought a 4 barrel edelbrock carb, and this one is manual as opposed to the partially electric VV.

I got a conversion plate for my 2 barrel intake. I was told that I needed to buy a distributor with a vacuum advance on it, so I did. Then I was told that this new distributor would require me to buy a new computer that had the correct outlet, and was advised to go to a junkyard and rip it out of a similar year ford. I did, from a 1985 f150. I am about to attempt to wire it all using the haynes electrical diagram for the 84-86 since thats the year I got the computer from. Is there any advice I can get for this?

So, it sounds like a DS2 conversion you're asking about.

What engine do you have? You should not need a computer. Any distributor with a vacuum advance does not use a computer. It uses a ignition module though. I hope you do not have a 300 six, those parts from a 1985 f150 are not going to help if you have a 300 six.

I spoke to a friend and he said that he made his super simple by running a two wires from the key, one to the battery and one to the starter solenoid, and a wire from the soleoid to the starter, and a wire from the battery to the distributor (or something along the lines of that). Does that seem more viable for someone of my low experience level?

You can do that if you buy a one wire HEI distributor off ebay for your engine. They took the guts of a GM HEI and installed them in a dist body that fits your Ford. People use them with mostly success. But you would run one wire from the dist to the keyswitch, not the battery, so you could turn the engine off.

The distributor you got, is it a old points type? That also would only require 1 wire from the key to the coil, and then the coil to the dist, but you would need a resistor in the wire between the key and the coil.

Old distributor:




This is the diagram he worked up. He said hes willing to help me but wanted it checked out to make sure its correct.


Also, is this the type of distributor you were talking about? HEI Distributor for Ford 5.0 EFI to Carb Conversionâ?? | Vintage Auto Garage

Thanks a lot!

If you have a 302, yes that distributor will work in the link.

He doesn't have enough wires hooked to the ignition switch. The switch should be fed by a hot wire, and it should have one wire leaving the switch going to the solenoid, and another going to the HEI dist or the resistor and coil like he is showing. His diagram is for a points type dist. Unless you use the HEI dist, you are going to need a ignition module also, along with the resistor and coil. It all depends on what distributor you buy.

Yes, I saw that at the last minute and went back and changed my post. Re-read it and see what you think.

You are referring to a starter solenoid correct?

I drew this one trying to follow your instructions

Also with this configuration there would be no need for a computer correct? And I ordered the distributor linked above, except on ebay for half as much. The fact that it says EFI to carb conversion worried me a bit but obviously it must not matter in this situation.

Yes, you new diagram is better. If you are using a universal ignition switch, the battery connection will go to "B" on the switch, the distributor wire will go to the "I" terminal on the switch, the small "S" terminal on the starter solenoid will go to the "S" terminal on the ignition switch.

What type of alternator are you using?

I saw you had the alternator in your diagram. If you leave it alone you should be fine, but it should have more wires going to it than your diagram shows. Just wondering about it.
