Igntion Breaker Points

[Matthew D.]

'63 coupe 327/340 with SHP. Anyone know the make/part # of the points and condenser? I'm assuming they are delco but coulnd't find any guidance in the tech/judging guide. Thanks in advance.

There are a number of different Delco ignition parts that will work. I listed some of the current numbers below that are readily available at places like Summit:

For points, I like the D106PS – terminals attach with a screw. There’s also a D106P; and D1007 with integral condenser.

The separate condenser is a D204.

I use rotor number D426R and distributor cap D308R.

I’m sure others will chime in with their preferred numbers.

Re: Igntion Breaker Points

Nice article in a fairly recent Restorer. My question is: are part numbers given applicable for dual point distributors like in the 340 hp 327 or are they different?

340 327 ok, the 283 2x4 bbl versions used the points that had to be adjusted with the cap off.

Matt,

Here is the draft Duke had written for the article that appeared in the Restorer.

NAPA Echlin Contact Sets (Ignition Points)
by Duke Williams and Tim Schuetz

For many years confusion has reigned over the various contact sets sold by NAPA under the Echlin
brand. There are six Echlin contact sets applicable to Delco single-point distributors not including the
"uniset" that combines the points and condenser in a single assembly. NAPA also sells a price leader
line called Mileage Plus and a couple of other contact sets in different brands.
You can see all them at
www.napaonline.com, and if you know how to use this Web site (which is a
your distributor boils down to the condition of your distributor, your
driving habits, and, perhaps, some experimentation. My bet is that a majority of single-point
distributors out there are in need of a blueprint overhaul. Sloppy endplay, excess shaft bushing
clearance, and wobbly breaker plates will not allow peak performance, even in base engines. If the
ignition system does not deliver a properly timed spark of sufficient energy for all operating
conditions, the engine will never achieve peak performance and fuel economy. It's that simple!
Nominal point life is about 30,000 miles, but varies widely depending on ignition system configuration,
condition, and operating conditions. Since most of our cars have low annual mileage accumulation, it
is a good idea to check rubbing block lubrication every couple of years, and while you're at it, check
point resistance and dwell angle. Dwell angle changes due to contact surface and rubbing block wear
affect initial timing, therefore checking initial timing is also a good idea after you have checked and, if
necessary, adjusted dwell. Throw in the idle speed/mixture adjustment procedure, and you have done
a minor tune-up in less time than a wash job.
Thank-you Tim Schuetz for providing the test samples. Tim did not want them back, so I auctionedoff
the standard breaker arm tension contact sets at our February Southern California Chapter
judging school with proceeds earmarked to the Chapter Charity Program. I retained the high breaker
arm tension contact sets for further evaluation.

Re: Igntion Breaker Points

I always just go to the NAPA counter and tell them what I need, I get what Duke describes.

Re: Igntion Breaker Points

Wow Tim, extremely informative, thanks for posting that. In an effort to be as close to original as possible I ended up buying a set of original still in the foil package delco points off fleabay (the D106P). We'll see how they work out otherwise Ill reference the article for something better. The burnt up points that were on there had the felt lubricating pad attached which I see mentioned. How important, in your opinion is the pad to have as far as operation and longevity?? Car is run about 500 miles a year.

Thanks

Matt -

At that rate, your new points should be good for 25 years.
