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.

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

By buddy - 13 Years Ago

Randy,

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

By randyh - 13 Years Ago

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

By randyh - 13 Years Ago

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.

By DANIEL TINDER - 13 Years Ago

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.

By slumlord444 - 13 Years Ago

Ford has done stranger things. Could have something to do with with what was the simplest to fit in the existing space without having to switch out more parts than necessary.

By GREENBIRD56 - 13 Years Ago

This photo showed up over on the HAMB recently - it is believed to be a Mallory conversion system for a Load-O-Matic. As discovered, it had two different point sets with opposing swing pivots. Hehe

Randy,

The dual point distributor in my 1957 312 engine is a COAF 12127 A and someone will have to help me in identifying it. Does CO indicate 1960 year? I matched my points up at the parts store and the Standard P/N FD8285XV points matched up perfect to the original straight line mounted dual points and were listed for high performance with higher spring tension. I installed them in my distributor and they work fine.

Would like to know the part number on the distributor housing and date code as I would like to compare it to my S/C passenger car dual point distributor.

Is this distributor a tach drive or conventional?

Dennis

Interesting. I see an inherent problem though (aside from lack of point interchangeability) in that loosening the common mounting screw to adjust one set would likely change the other set's gap. It's hard enough to get the gap exact when you can tighten both ends down. There is plenty of room on the other dual conversion plates I have for identical point sets, so can't understand why Mallory went this way. Unless, there is some non-obvious advantage to pushing one arm and dragging the other?

Thanks Dennis for the explanation and identifying my distributor. Just below the COAF 12127 A is another number Y 9KC or O and there was a paper sticker showing it as FoMoCo remanufactured

By randyh - 13 Years Ago

My phase 1 distributor is number FEH-12127-E. It takes one curved point set and one straight set on the side where the vacuum advance commects. I will try to post a picture in a day or so. Randy

By buddy - 13 Years Ago

Randy,

Yes, it's obvious we have different distributors since one of your points are curved and both of mine are straight. I had been unsuccessful in identifying the distributor in my 57 312 but thanks to Dennis it was built for a 1960 to 62 292 and at some point it was apparently converted to dual points.

By randyh - 13 Years Ago

Try to put the NAPA points in, the straight set, NAPA CS754, doesn't fit correctly. Although screw holes line up, the hole furthest from the contacts runs out of room before the rubbing block hits as you can see in picture

I need set that has a little curve to it, Anyone have any ideas? Randy

By randyh - 13 Years Ago

My father doesn't remember replacing the plate. If someone did they did a nice job of putting the adjustment hole with slot in it at the contact end of points. I may have to enlarge the slot in the end if i don't find the correct ones. Randy

By GREENBIRD56 - 13 Years Ago

How does the condenser mount on the Ford version of the dual points? Is the external condenser still available? The fat one shown in my earlier photo is no longer available from Mallory - and the fellow who owned the outfit was also struggling through finding the necessary repair parts.

By PF Arcand - 13 Years Ago

This subject is confusing! I have a box of what were supposed to be 57 (& up) point sets. However, only one was and there were other points, both left & right facing that were straight based. I've assumed that some were regular 1955-56 Loadomatic points & or 6 cylinder ones. But one thing that further confuses the issue is that I've seen references to Loadomatic distributors, even in an article, which weren't, they were 57 & up distributors. Anyway, I don't know if any of this is helpful or not?..

By randyh - 13 Years Ago

The condenser B7A-12300-B mounts on the outside underneath opposite the vacuum advance unit. From what I have been able to figure out it is the same design as the standard V8 condensor B7A-12300-A or -C. I don't know why it was a different part number. For the points B7A-12171-B is refered to as closed bracket and the other B7A-12171-C is refered to as open bracket. Randy

I dug out my distributors. My passenger car supercharger dist is FEH-12127-E, date code is 743. It has straight and curved points and a vacuum advance diaphragm assy, but the port is plugged.

I have another dual point dist, FEK-12127-C2, date code 6A2, it is a tach drive with straight and curved points. However, I don't think it is a T-Bird based on the drive cable length, a bit over 47". Someone thought Turnpike Cruiser, but from the date code wouldn't that be a bit early? Possibly some race application 312 260 hp LOL or maybe a truck? Anyone know the original application?

I also have one other dual point, C0AF-12127-A, date code OMB, two straight points. Sounds similar to the one that Buddy was asking about. Coincidence they have the same housing part number or was there an application somewhere?

Regards,

Dennis

I have heard the condenser has a different capacity rating. I believe the S/C condenser has a capacity rating of .21 - .25 mfd (micro farad). Does anyone know the capacity rating of the conventional V8 condenser? I have an original Ford condenser on my S/C distributor, maybe I can figure out if something is different. Physical size, they appear to be the same, but electronically they may be different.

Dennis

The 1960-64 Ford Parts Book lists C0AF-12127-A for a 60-62 292 engine. Somewhere it must of been converted to dual points. On the body near the part number there should be an alphanumeric manufacturing date code. "C0" indicates the decade (C=196X) and model year (0) of the component. A= Full size Ford, and F = Hardware and Accessories Division Product Engineering Office.

Dennis:

In my Master Parts Catalog it shows FEK-12127-C as fitting 57 Turnpike Cruiser 368 engine w/o tachometer not serviced in assembly use FEK-12127-E Confusing as you say that it is a tach drive distributor you have unless the C2 was an update from the original 12127-C model.

FEK-12127-E is for the same engine with tachometer

FEK-12127-C2 is what it reads and it is a cable tach drive. Any idea why it would have such as early date code, 6A2, Jan 1956 for a 1957 Mercury?

Will this distributor work in a 292 or 312, or is it 368 specific?

Regards,

Dennis

By Dennis K. - 13 Years Ago

John,

Counted the teeth on the tach drive dist and it is 15. The 312 S/C count is 14.

Were any of the 368's dual point, or do you think was this converted?

MARVH, thank you for ID'ing the dist and John for the tooth count info.

As I have a 292 converted to Duraspark on the engine, these will go back into hibernation.

Regards,

Dennis

I noticed in your earlier post shown above that the vaccum advance was plugged on the FEH 12127 E distributor. When I bought my 1957 312 it was complete except for the carburetor and the vacuum advace on my COAF 12127-A distributor was also plugged. I found that baffling and was curious as to what application you would ever plug the vaccum advance?

By slumlord444 - 13 Years Ago

The FE and 289 Ford factory dual point distributors were centrifical advance only with no vaccum advance. When converting the Y block distributors to dual points using the FE parts you plug the vaccum advance and re curve the distributor accordingly. Been running mine that way since the late '60's.

By buddy - 13 Years Ago

Thanks for all the advice and information. I probably need to check the advance curve for sure on my distributor.

By Dennis K. - 13 Years Ago

xxx

In the S/C Dist the straight points have part number FR-151 S and the curved points have FR 152 S stamped on it.

Both have a mfg logo on them "CP", more of a "C sub P", like in a math equation.

Can anyone ID or cross those numbers over to another manufacturer or source? Trying to help Randy H out.

Dennis

By 34xracer - 13 Years Ago

Hi guys. I had to throw in my two cents on this. I just finished tearing down a 292 Yblock that has set in the timber for the past 40 years. It had been put in a 51 Ford convert, and was a half completed custom project that was abandoned by the owner. Anyway, the motor is trash from being full of water, but I was able to get the tach drive distributor out in one piece. It has the FEK-12127-C2 number on it, and is single point. Date code is 6O3, and it's a 14 tooth gear. The fact that it has the dipstick in the side of the block (not the front cover), and casting numbers B9AE, I believe this is a 59 truck motor. So, maybe there is something to the truck tach drive guess? I'm assuming that physically this is the same as the tbird tach drives, just the specs are probably a little different? There was no cable on this, a small cover had been made for the hole.

Unsure

By PF Arcand - 13 Years Ago

Your likely right about it being a 59 (or 60) truck engine,with tack drive. It may also have a rear sump pan. Was is a 4 bbl unit by chance? To bad you can't salvage any of it?

By 34xracer - 13 Years Ago

Yep, it had the rear sump pan, even at that, it was 'modified' (ball peen) for tie rod clearance in the '51. It had the wide-base 2v carb and manifold,the carb is garbage. I was able to salvage the cam (looks stock) and crankshaft (R .020, M .010). The crank is borderline useable as is, or easily ground to the next .010. Motor was so stuck that I had to torch the rods to get the crank out Crying

By Hoosier Hurricane - 13 Years Ago

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.

By Hoosier Hurricane - 13 Years Ago

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.

By Hoosier Hurricane - 13 Years Ago

Randy:

I have a hunch that someone along the line replaced the point plate, and used the single point plate instead of the correct one, then hand drilled the mounting holes for the points. Got the pivot hole off a little. Probably slotted the hole in the points base so the screw would go in. Looks like you could do the same, even if the mounting hole became a slot instead of a hole.

By Hoosier Hurricane - 13 Years Ago

Dennis:

I understand the Lincoln distributor will work in a Y block if you put the 14 tooth Y block gear on the Liincoln distrubutor. The Lincoln has 15 teeth I think.
