    The Ford distributor tech tip is going to be a big help as far as the ignition goes while using the TBI fuel injection.

    http://www.justinternationals.org/ford-hei.htm

    But in the write up it says your using the stock cap and rotor do to clearance problems at the thermostat. How much of a clearance problem is there? Could it be milled out?
    The new cap has got to handle spark better!:confused:

    Clearance

    I should have a cap in the garage. To make things clear I will put one on one of my scouts today or tomorrow and get some pics.
    I have heard it is not a big problem with the IC392, but since I don't have one I can't verify. The IC392 is supposed to have a revised bypass hose and outlet that gives it more room.
    stand-by for more info on the clearance.

      Have you ever seen the thermostat housing on the 1980's?
      They don't have the big rise.
      Would that help?
      I'll try to get a picture up...

        Here is the cap.

        Making it clear should not be to big of a problem. Then it's just a new set of plug wires!! As you can see it hits right next to the temp sender. should be enough to grind there.

          Question

          Is there a way to get some better pics? Good pics can make a med job into an easy job for the dist weak. (like me) I am very interested in what you guys are doing here.

          How is the fuel injection working? Also what computer will you need to get if you do the dist mod?

          Item 14 is a little confusing to me?

            pics

            I'll ask santa for a new camera. (or have TORC send me his).
            I used my 99.00 trail camera since I broke my other one. good for the trail, bad for close ups.

            As for step 14 pls explain what is confusing. Keep in mind that when you have the parts in front of you things will be a lot clearer.(no pun do to bad pics)

            If you have never set the timing or are unsure about setting the number 8 on TDC, then to be honest you should get assistance before starting this project. It takes mech and electrical knowledge to complete. (basic automotive skills not engineering)

            Not sure what you are asking concerning the computer.
            The ecm of choice for the fuel injection conversion is the GM 1227747 for the V-8's. It came in chevy trucks. late 80's to early 90's. I have also used the car version 1228746.

            As for how it is doing.....
            I love it. I am still playing with the chip tuning trying to get as much performance and MPG as I can. I actually got it to ping tonight which means I finally got the timing too far advanced. It's a good thing for tuning but a bad thing for engines. The nice thing about this system is the computer will detect the ping and automatically reduce the timing till the ping goes away or the conditions change(gas off the floor).
            and this is just on the street scout.
            The trail scout is another subject. no flooding, no starving, no burps when trying to hop over rock ledges or roots, just a smooth throttle.
            I have already converted another club members scout and have a couple more waiting for the funds and time.
            Hope this answers some of the questions. I'll try to take some better pics.

              I mean what replaces your gold box if you are not going fuel injection?

                Ignition

                Use the whole ford duraspark ignition.(Dist pickup and box) The box is usually mounted on the fenderwell of the ford. Just pull both from the same donor car in the junk yard. since you need a V-8 dist you will have the right ign box already and the wiring connecting them. You will need to check the wiring diagram for the ford, but if I remember right it only takes 2 or 3 wire to hook the system to your car. I think it was a red and a white wire. I'll have to go double check. then just make sure it is properly grounded and the surface you mount it on is properly grounded. Bad grounds will cause it to overheat and loose all the rubber potting compound out the back, just like the gold box ignition.

                  Hey I found



                  http://www.jason.fletcher.net/tech/d.../duraspark.htm



                  First the distributor, the key here is to get a distributor that is compatible with your cam type, has vacuum advance, and has a decent mechanical advance curve. What this means is if your using a roller cam you need a steel gear - see the Ford Motorsport catalog or just use an '85 Mustang 5.0L GT distributor for a 5-speed. I paid about $90 for mine from the Ford dealer rebuilt. Also the '85 Mustang distributor has vacuum advance and a great advance curve straight from the factory. If you are using a flat tappet cam your first choice should be an '82-'84 5.0L Mustang HO distributor. This distributor also has vacuum advance and a good curve. In the end any '77-'84 302 distributor will work with as long as the car was carbureted (NO CFI - throttle body injection), just don't forget to use a drive gear that is compatible with your cam. Get your distributor advance recurved as follows: centrifugal advance - 0° @ 1,300 rpm, 11° @ 2,000 rpm, 20° @ 5,000 rpm; vacuum advance - 0° @ 4.5" Hg, 11.5° @ 8" Hg, 20° @ 12.5" Hg.
                  What kinda cam do we have? I think I would like to use a carb for now and go to your TBI system later when I build a 392.

                    Sweet!!!

                    Keep in mind you are only using parts of the ford dist so all the stuff about advance curves wont apply to you since you will still be using your stock dist . Just leave the springs in the bottom like they are. Just pull the reluctor and the base plate from the ford and install as per the directions.
                    If you look at the wiring both wires go to 12V.
                    Tie the red wire straight to you ign sw. there is a wire going to the gold box and to the dist now that is 12v when the key is on.(R)=run.
                    The white wire is tied to the (S) term of the the starter solenoid. Most scout II's it's the small white wire going to the starter. S=start
                    Notice the dist grounds through the ign box so make sure it is grounded good.
                    PS: be very careful on color codes. sometimes ford changes the color of a wire at a connector. (look at the white wire)I am talking colors at the box!

                      I think some clarification is needed here. There are at least three different D-S modules that I'm aware of. They are ID'd by the color of the plastic strain relief the wires enter the module thru. The most common one, and the only one I'm familiar with, is the blue strain relief version. This module does not ground thru the case of the module. On some models Ford mounted it to a plastic fender liner. Notice that there are three wires going to the pick-up coil strain relief, but only two from the strain relief to the pick-up coil itself. The module grounds thru the strain relief hold-down screw. That pair of metal rings are connected to the third wire. The Black w/Orange and the Black w/Purple are the pick-up coil wires while the Black w/zip is the module's ground.

                      Something else to note: In some instances the engine will continue trying to start after the ign switch is shut off. This is caused by a back-feed current running into the module's 'Start mode' wire, i.e. the wire labeled as being red in the above diagram hooked to the ign switch. This appears to be a problem similar to that which MSD has with some GM vehicles not wanting to turn off (That diode they supply). The vehicle will start and run w/o this wire connected to anything although it usually only catches after you release the key from start mode.
                      Also, I have not experienced any problems with powering the module directly off the "+" terminal of the coil, even though that means the module is getting reduced voltage. I drove my DD '66 300ci six powered Econoline van wired that way for 5 years without any problem.

                        Donor car

                        If you pull the whole system from the same V-8 you won't have to worry about most of that.
