Changing points and condenser (dual points?)

[Blue71]

I am getting ready to change the points in the '68 that was sitting. It has the dual points inside the distributor. I looked at my '71 and '74 and both have the single points. Should my '71 and '74 have dual points in there like the '68? I only bought one set of points for the '68, so do I need to get another set to keep them dual, or what? Someone set me straight on single and dual. Thanks Much,

I'm pretty sure EBs did not come stock with duel points. Duel point distributors were for High performance applications. If I remember correctly, if it has duel points, you'll need to replace both sets....

;D ;D ;D You will need to find what brand it is as to setting the dwell and gap good luck. %) %) %) Bill %)

Ford dual point dist. (like on the hipo 289/271) did not have a vacuum advance unless there is one I dont know about.
You should replace both sets and the condenser. I used to set mine with a dwell meter.
Good luck

Thanks for the tips guys.

J.R. or anybody else...........Could this distributor be the stock distributor or did someone do some sort of upgrade more than 14 years ago. Truck has definitely not run or been touched in 14 years or more. Just wondering if any of the Bronco 289's had the stock Dual Points? Would you use the same points as you would with a single points setup? Would you gap them different than .017 since there are two sets of points?

Let me know.

Thanks Much,

I would guess a paycheck that it was not stock. As Mr Joe posted, they were for high perf apps in the mid-late 60s. I would think somebody with a Mustang/Falcon Fairlane would pay good money for it.....check Ebay.

I dont think they use the same points. I think the points in the duals had stronger spring tension to prevent bounce. I never tried to use the stock (single) ones in a dual. They gapped the same. Best way to tell is ask the parts guy to see if they are the same. It's been 30+ years since I had a dual point and my memory is a little fuzzy. I would not try to use the stock ones or try to use just one set. If you dont want to be bothered, sell it and stick in a standard.

The benefit to a dual point is the high performance aspect, and better output at high RPM. A stock engine really doesnt need that.
I would wonder what the engine itself is. Visible on the outside:

1) Fatter crank damper, by about 2.5x

2) Heads (without taking apart), small tab on the leading edge of the head
near where the accessory bolts go in.....there;s a number hipo heads were something like 18 to 21 or 22. If yours are in that range, get excited. Pull the valve cover and see it=f the rockers are threaded.

3) Dual point

4) the rest is internal, crank, cam, rods................

Let us know!!

My 68 had Duel pt too. I think it came out of a mid 60's stang and was made by Mallory for Ford. It does have a vacume advance.
The points are different as I'm sure you noticed.
Just take the points in and ask the parts guy for 67 mustang duel points and compare. (That just happens to be the year I used you can probably use other years as well)

Pretty much ditto everyone elses answers Dual points were not stock on Broncos it was either swapped on or ford did offer a conversion kit for stock distributers p/n D1AZ-12A132-A. As for points you can use either standard points or the higher tension ones I always used the higher tension ones when I could even in stock distributers although the really have no benifit unless your running high RPM's but they seem to be better quality. I'm sure after changing a few sets you'll start looking at electronic swap.

I had one of the Ford Dual point distributors in a Mustang and I am positive it did not have a vacumm advance. I do remember running it with only 1 set of points for a short period of time, but I can't remember if you had to anything specific to get it to work that way.
