Mallory Ignition Parts
 
Does anyone have any info on any of the Vintage Mallory Coils or the CD ignition systems?

yea, a stock Chevy distributor curved and set up on a machine is just as good.

Sam, I'm talking about the coil and distibutor that mockingbird has on his Deuce.

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!

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.

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.

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!!!!!

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?

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.
