Mallory Ignition Parts
Does anyone have any info on any of the Vintage Mallory Coils or the CD ignition systems?
|
Re: Mallory Ignition Parts
yea, a stock Chevy distributor curved and set up on a machine is just as good.

Re: Mallory Ignition Parts
Sam, I'm talking about the coil and distibutor that mockingbird has on his Deuce.
|
Re: Mallory Ignition Parts
Jed, do yourself a favor, if the car is to be street driven and enjoyed, follow Sam's advice and custome tune a stock dizzy with a vacuum advance. You can still add any CD kit, cap and wires you choose.
You know who can help dial that thing in! |
Re: Mallory Ignition Parts
I wanted to call him tonight! Lol. But got too late.

Re: Mallory Ignition Parts
Hey Jed,
My mallory dizzy in the Deuce, altho it has 2 sets of points, is not really any more of a hot set up, by itself, than the stock GM. Each set of points just alternate taking the spark from the coil. It is mechanical advance only. The dizzy has just one condenser for both sets of points. The benefit is longer lasting points (theoretically lasting twice as long). I believe my Mk II coil that I use with this dizzy is a bit hotter than a standard GM coil, though. What I have learned of most recently is about the rev/pol dizzy and coil. My understanding is this dizzy has 2 sets of points also but, they each fire at the same time and produce a more intense spark at the spark plug as a result. There are TWO condensers on this dizzy - one for each set of points. I have tracked down an nos YC-310 rev/pol dizzy (with two brass external condensers) and I will continue to look for a Mallory rev/pol coil to mate to it. This should be a noticeable performance upgrade. BTW, the rev/pol dizzies and coils are a bit more rare and expensive than the standard stuff. I will save this for a future day two project to be named later! I think there is a Mallory switch for the cockpit that allows you to switch the polarity of the coil for street/strip use, but am not sure exactly how this works. |
Re: Mallory Ignition Parts
Sam, I didn't want to let this out yet, but I have an NOS YC-310-HP. Not any cheaper than the new ones. Dated Aug 71. I also have an NOS Mallory CDNA-1 on it's way. Dated 69. I wanted to know what coil can be used with this combo? I almost had an NOS 28675 coil.

Re: Mallory Ignition Parts
Cool Jed. is your 310 a rev/pol w/ 2 condensers? I am not familiar with cdna. Mike our new sponsor has done some beautiful restos of mallory systems. I am pretty sure he did Mark Murphy's Mallory set up. Some other brainiacs around here should be able to advise you on various set ups and combos.
I like where you are going with this Jed-i!!!!! |
Re: Mallory Ignition Parts
Sam, it isn't a Rev Pol. It's just like your YC 465 HP but without the Tach drive. The CDNA is an early Mallory Capacitive Discharge ignition. Kinda like a 6A or 6 AL of today. There is one coil that I found that is for a CD ignition, but not sure if it's right for this setup?

Re: Mallory Ignition Parts
I took this off of HAMB (btw, the "Double-life" is what I have on my Deuce right now):
<span style="font-style: italic">Double-life: 4-lobe cam, two separate sets of points connected together with one condensor. This is wired to a normal coil. The only benefit of this over a normal single point distributor is that the points last longer as each set is only firing 4 times per revolution. Rev-pol: 4-lobe cam, two separate sets of points, each with their own condenser and wired to separate primaries on the special Rev-pol coil. This coil has a single secondary terminal that connects to the distributor cap. My guess is that this offers some of the benefits of a dual-coil setup without having to use two coils and a special distributor cap. Hence, if you have a Rev-pol, but can't find the special coil, you can remove the second condenser, wire the points together and run it with a normal coil. </span> <span style="color: #009900"> <span style="font-size: 14pt"><span style="font-weight: bold">Any of you smarty-pants out there confirm this or expand upon it?</span></span></span> [img]<<GRAEMLIN_URL>>/scholar.gif[/img] |
Re: Mallory Ignition Parts
More info found....
<span style="font-style: italic">...the dual point ignitions had point sets that are are offset a few degrees on the point plate... one set opens the circuit and the other set closes the circuit therefore giving the coil more saturation time (dwell) in the same 30 degrees of crank rotation as single points. I had a Mallory Rev-Pol distributor in my '56 Chevy which worked very well with 11:1 compression ratio and at 6500 RPM. Pontiac introduced the transistorized ignition system in 1963 and that system was far better than any of the dual point systems.The Mallory Rev-Pol distributor had dual coils and dual external capacitors. The Rev-Pol dual points were operated by a 4-lobe distributor cam which increased coil saturation time and reduced point bounce at high RPM. With a point type ignition, coil output voltage is reduced because coil saturation time decreases as the RPM increases and that is when dual points will help maintain coil saturation time at high RPM. Today, one of the best replacements for a point type ignition is a Pertronix electronic coversion kit. The Pertronix kit provides the same amount of coil saturation time at infinite RPM as it does at idle RPM. However, that kit is not as good as a stock GM high energy ignition found on cars today. The HEI systems on GM vehicles is not necessary for high compression ratios or high RPM but it is required to fire the lean fuel-air mixtures that were mandated by the EPA to reduce emmissions. </span> |
Re: Mallory Ignition Parts
Jed-I use that black Mallory coil that bolts to the firewall. They look great for the Day-2 look. My stock single point went to 8 grand with no problems back in the day. Accel points with a good distributor curve set-up and you are done. I bet your motor will not see over 6,000 much so you will be fine in any case. I have a big yellow Accel coil in the box if interested and also early Accel wires that were never used. Come on over!

Re: Mallory Ignition Parts
Sammy has lots of cool stuff!!!
|
Re: Mallory Ignition Parts
Okay, who's run a dual point dizzy and wired in a switch to eliminate the first set of points to retard ignition timing on the top end? Don't see how you could do that with a double life.
|
Re: Mallory Ignition Parts
retard timing on this Site?
|
Re: Mallory Ignition Parts
Flat out foot to the floor!

Re: Mallory Ignition Parts
Paul - don't think you can do it with a "double life". Altho there are 2 sets of points, they are being fired with the same coil (single winding) at the same time (or nearly so) in order to increase dwell, whereas the rev/pol is two distinct circuits (2 coil windings, 2 condensers, 2 points).

True Sam. It won't see 8 grand with this motor. I would be lucky enough to get it up to 5 or 6 with an auto?? The cam is good for 5500, so maybe? |
Re: Mallory Ignition Parts
a pure stock Chevy unit is good enough for that Captain Jed! Don't get to trick on yourself my son.
|
Re: Mallory Ignition Parts
Just got my 40 yr old Mallory 28675 today. Its amazing that something this old works better than my 5 yr old coil. Cleaned it up and tested it out on my 55. The tired 265 ran 3 times better. [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] They don't make things like they used to.

Re: Mallory Ignition Parts
Mankinds' greatest mechancial achievment is the General Motors HEI Ignition!

Re: Mallory Ignition Parts
True Mark, but I'm a glutton for punishment. I highly doubt that this stuff will stay in the car?
|
Re: Mallory Ignition Parts
Got my Mallory CDNA-1 unit this week. From what the instructions state, it is just like a modern ignition box, but 1969 vintage. Pics to come soon.
|
Re: Mallory Ignition Parts
Good deal Jed. Does this still require a separate coil?
|
Re: Mallory Ignition Parts
Coil #28675 Sam. And you can detach the box to run it with just the coil. The box instructions are dated 9/69. SWEET!
|
Re: Mallory Ignition Parts
Cool - I have the 28675, "markII" I think, on my Nova too. Let me know what kind of performance improvement you get.
|
Re: Mallory Ignition Parts
I will do Sam, but it will be a long while before my Tone Blue is on the road.
|
Re: Mallory Ignition Parts
That Mallory CDNA-1 is a "off road" unit.
|
Re: Mallory Ignition Parts
When Scott S brought his recently acquired 1969 Phase III Chevelle (originally owned by Joe G) out to the Solid Lifter Showroom this year, he actually had the original CDNA-1 box with him. That thing is seriously heavy!
That was the original Phase III ignition on Joe's car, and later updated to the popular finned box. I don't recall the story of why the box was updated, but fortunately it was stashed away and stayed with the car. |

Just like the Z-28 Trans Am cam? Or anything Hi-Po in CA? Lol Pxtx, this thing has some weight to it. Its all sandcast alluminum. |
Re: Mallory Ignition Parts
Post #43859 from JoeG in 2003
Hello pxtx, 1968-1969----The MALLORY CD IGN. called the "Magic Box" Around 1970--PhaseIII CD[Jacobs Electonic Unit] was introduced and used for a while. After that, I guess the one JoeC is showing After that the Energizer Bunny. -----JoeG Maybe we should either bump this thread posting pics of your Magic Box or stat a new one in he Day II section under ignition systems. https://www.yenko.net/ubbthreads/ubbt...852&page=1 |
Re: Mallory Ignition Parts
You got the bump.

Re: Mallory Ignition Parts
Hi Guys. That coil pictured....is there a date on the instructions? That is not of the same vintage as the distributor. The Mallory logo is the later version. That coil was avail through the 80's.
If anyone has questions on old Mallory stuff. I have a large collection of NOS and used parts, distributors, coils, kits etc. and literally binders of original sales literature and catalogs from the 30's through the present. The Mr. Gasket group even refers their inquiries on vintage stuff to me on a regular basis. Mike |
Re: Mallory Ignition Parts
Thanks for the offer Mike. I, and others, will have a few questions I am sure.
|
Re: Mallory Ignition Parts
Mike, I was told the coil came off an MG. No dates. Everything else is dated 69 and 70.
