I am rebuilding the original dual point distributor for supercharged 312,  does anyone know what the part numbers are for both set of points?  The 1957ford site says that one set is the standard V8 set and that the second set is for a 6 cylinder.  thanks, Randy

Don't know the part numbers but unless you REALY want to keep the inside of the distributor totaly original, I would go with a Pentrox Electronic Ignition conversion. Have one in my E setup car and would never mess with points again. You might try the points for the later model Ford dual point distributors. I had converted my single point setup to dual points using a later model Ford breaker plate and points before I went to the Pentrox.

One set is from a '49-'56 V-8, the other is same era 6 cylinder.  I believe the NAPA numbers are CS749 and CS 750.

Thanks for info I will see if they fit.   This is an original Phase 1 Custom, I am trying to do as original restoration as possible.   Randy

I purchased a set of dual points at my Fisher Fisher Auto Parts (Federated Auto Parts) store for my 1957 dual point distributor and they were listed for high performance distributor with higher spring tension.  They are the Standard Blue Streak brand and the part number is FSD8285XV

Randy,

I got the part number off one letter.  The correct Standard part number is FD8285XV

John, checked those numbers out at NAPA they don't look correct as they are for right and left hand points. I believe these had two different points but both had same orientation.

Buddy, I will have to cross reference that number, I checked where standard parts are sold and it doesn't look like any around Pittsburgh. Thanks, Randy

Randy:

Egg on my face!  The only dual point setups I have seen from that era used the points I referenced.  Got my parts book out, the blown Ford used a B7A-12170-B and a B7A-12170-C.  Those numbers are not listed for any other engines of that era.  They may be unique because of higher arm tension, but physically look the same as another points set of the era.  I just don't know.

I have an old NAPA ignition catalog that shows pictures of their products, maybe you can pick out points from such a catalog.

Stopped at NAPA store today and went through their older ignition catalog, I found the two Ford numbers listed, B7A-12171-C under CS754, the straight set and B7A-12171-B under CS755, the curved set.  Look to be correct.

Don't understand why any dual point distributor would benefit from dissimilar points set/pairs? Seems like an unnecessary complication. The dual point conversion kits I've seen for Loadomatics all use identical/interchangeable points.
