  • I'm trying to do a "holley point / ford duraspark conversion"...help!

    I could't get any distributor besides the holley points one at the bone-yard.

    (I have all my ford parts)

    How do I get the "point lobes" thing (maybe it's called a cam, I don't know...) off the shaft? Is it pressed on? Does it come off the same way the reluctor on the holley gold does? I am wary of the grinder, I am not sure how to get it off evenly that way with-out a lathe. I don't want to break the whole thing, they are hard to find.

    Is it the same as the prestolite conversion? Does it have to be machined? It's an all day trip, but worth it if that's what it takes.

    Oh, the duraspark box was $20 at the bone-yard, so I went to Auto-zone and got it new, with life-time warranty for $16.

    Thank you for all suggestions..possum scout

    reluctor

    Before you get too worried about it, put the new base plate and pickup in the point dist.

    then slide the reluctor down over the top of the shaft.
    I'm assuming the base plate will fit over the point lobe.
    Then slide the reluctor over the upper shaft to see where it lines up on the magnetic pick-up.
    Something I have also done is flip the reluctor upside down and put the long tab down to make it line up with pickup better.

    If the reluctor will line up then your good to go.

    I don't have a point dist here to compare, sorry.


    If the base plate will not go over the point lobe then you will have to use the bench grinder or something similar to grind it down.

    The prestolite conversion is totally different.

    If the point lobes are in the same place as the GB reluctor then you should be fine. I have put the ford reluctor on top of the GB reluctor and had it line up with the pickup.

      I guess I am calling it the wrong thing?

      It is on the shaft, it looks like a nut.

      oh, wait a sec... we turned it (the reluctor) up-side down, and the rotor fits now.

      Are we just needing to grind that nut thing down enough to clear the plate?

      Or are we going for a machined finish? If it doesn't matter how "round" that thing gets ground, then we're going to be fine (the other half used to be a professional "grinder"). Anyway, if the reluctor can go up-side down, and the grinding doesn't have to be too precise, this will work!

      thank you,

        You don't need a machined finish.
        Just make sure the lobes are small enough to not stick out past the center of the reluctor. You don't want the pick up to think it is another tab on the reluctor(another cylinder).
        Just make sure the tabs on the reluctor line up with the metal tab on the pick up.

          it's going to work!

          Well, we have been taking turns grinding it down with a grinding wheel on a drill. My hands are still "jiggling", but it's almost ready. Thank you!

            keep us posted.

            Let us know when it is running.
            Don't forget you have to set the reluctor after the dist is in the motor. Set it on #8 10* btdc (3rd mark)then pull the old dist and drop in the new one. Then set the base where you want it to point. line the reluctor up with the pickup then tighten set screw. then tighten the dist hold down.

            adjust timing to taste!!!

              wiring problem....

              well, everything is going great with the distributor, but the wiring harnesses at the bone-yard were all junk. what gauge wire do I need to use?

                Glad to hear it.
                18awg should work fine.
                I think there is only 2 or 3 wires that need connected.

                It's been awhile but I don't think it was many other than from the dist to the box.

                  yippee! Distributor is built (used 2 s/s set screws) .

                  Now, will the duraspark cap fit with-out grinding the thermostat housing?

                    No.
                    You will have to grind right in front of the temp sender.
                    But if you do watch how deep you go!!!
                    I run the stock cap on mine right now.

                      coil upgrade?

                      Should I up-grade to something like a ford tfi coil? or stay with my accel super coil? which is hotter?

                      oh, and how much material would I have to grind to fit that ford dist. cap on there?

                        Changing coils is up to you. I run 1 on the stock scout coil and my other on the GM coil. I plan on upgrading to the TFI someday but don't feel like wiring in a ballast resistor just to run it.
                        I do have a big yellow accel super coil on the shelf.
                        guess i could forget the second battery and mount that big thing there!!!!

                        If you go with the DS cap you will have to go with different wires like the 454 set or the prestolite set due to the ends on the cap.

                        It takes about 1/8 to 1/4 inch to clear the cap. It's close to the water jacket on the manifold so use caution.
                        If you still have the stock wires and cap there just start with them till you get it running then upgrade a little at a time or when you need to replace the cap. just my opinion.

                          OK:) Thank you for all the help! I'll just run the stock cap on it for now. My wires are from Summit, I got them in Reno. They are fairly new.

                            Used to stop there each time I made the trip from Lemoore, Ca to Fallon, Nv.

                            Good wheelin out there that's for sure.
                            and down 14 to dove springs and red canyon.

                              Hey, familiar "stomping grounds"! I used to live in Stagecoach NV.
                              A "blink and you missed it" town on the 50, about 28 miles westerly direction from Fallon. Ran channel 21 on the "base station c.b.", channel 19 too. I had a big PDL2 antenna, spoke to the Lake, Fallon, Reno, and Carson all the time, with-out special conditions..rambling about c.b...sorry
