Put the old points in the garbage where they belong and replace them with PERTRONIX electronic conversion. Rid your self of stupid useless points, condensor and regular up keep of those said useless items and there up keep. The conversion is a direct bolt in with no mods what so ever and you never have to concern yourself with DWELL adjustment ever. Up to this point i have converted my last five oldies and it just mystifies me why anyone would want points in their oldie. Unless your vintage ride is a museum piece or just sits in the garage collecting dust all year long. Cheers.

He said I would be best to find a old 350 Delco rotor.

 

 I thought you were talking about points.  How did you jump to a 350 Delco rotor?

I have to disagree with long stroke. I have had the same set of points in my 55 since 2004 over 10,000 miles and no trouble in the 261 six cylinder. I have seen two sets of Petronix ignitor ignitions fail one in a flat head Pontiac six and another in a small block chev. The old flat head the owner forgot the key on the on position and the Petronix fried. The small block for no know reason. If you want to convert to Electronic Ignition I would suggest getting a GM HEI distributor and wires as a complete unit. Inexpensive used and a lot of voltage appx 60,000 volts. You will also need the correct wire connector plug in from a parts car. I am old school and still use a timing light and a dwell /tach meter when setting up a point style distributor. AC Delco still have points condenser rotor and distributor caps available. GM use to have a set of heavy duty points available that would take 8000 rpm without breaking down. Points style distributors were used in millions of cars. Al

 I'm with you Al. 

It's been decades, but it seems to me I did convert one car I had in the 70's to electronic ignition, and that car was never licensed, it only saw the drag strip. The only set of points that ever failed me was in the garage on the black 66 Grande Parisienne I sold a few years ago to Tom in Edmonton. And they fried because I forgot the key on for a week. 

Points and condenser have never left me on the road, so even if they do now I'd still say that's better than just about any HEI or any other electronic conversion I've ever seen. I don't understand why anyone would need to have an electronic ignition to put up and down the road to church and car shows on Sunday. A set of points will do that just as well.

I do the same setting up, set the dwell with a meter and timing is with a light/by ear combination.

Petronix Ignitor is a very good option, maintains original look but converts to electronic ignition. Pretty easy to install yourself as well.

I try to please those on both sides of the discussion (but I'm not a politician). I installed Petronix, mainly because I have little spare time for regular maintenance, thereby saving me checking the points periodically. However, just in case, my very high quality set of points reside in the trunk with the travelling tool kit!

The problem I have with HEI is they can let you down on the side of the road and the fix is not as easy as replacing a set of points.  The pickup in the HEI has a white or beige wire and a green wire.  One or both of these fine wires are known to break inside the casing so you have no visible signs anything is wrong.  Sometimes you are pulling away from a stop and the car up and dies, often starting back up, but quites when you go to pull away.  Saw a guy like this on the side of the road last year and everyone was telling him it was a gas problem, NOT.  In order to change the pickup you have to pull the distributor, remove the gear and pull out the rod.  To set them up properly you need brass fielder gauges.  Yes, the HEI ignition system is less effected by wet conditions and may even give better fuel mileage but I'm sticking with points.  Back in the day when I had HEI ignition systems I always carried the necessary tools to do this repair on the side of the road.  Point systems will usually give you signs your engine isn't running properly, HEI not so much!  I'm not familiar with the after market system that others have mentioned so have no opinion on it.

My opinion very much is akin to this;
Pertronics, is just another electronics conversion that is destined to leave you stranded.

I don't know that I agree with the assertion that you cannot get good points, because last I checked, you can still buy good stuff without having to go to new old stock components.

I briefly ran an HEI in my (former) '73 Firebird, then it crapped the bed - I did diagnose it as a bad magnetic pickup, but shortly there after I put a points distributor back in and have only run points in my calssic's since that time.

I sell my HEI distributors, and keep points - which as mentioned are easy to diagnose and repair - and will never leave you stranded on the side of the road.

I generally these days chalk up any stigma against points to people who generally don't know how they work, or think that because it's old technology, it must be unreliable.

Each to his own and what ever turns ones crank but i have had nothing but PERTRONIX conversions for about 20 years now on a number of vintage cars and never never never had a single issue. My 57 Pontiac's 261 has had the system now for about 18 years and i put 4,000 miles a year on this motor. Like others i keep a set of points and condenser in my tool box in the trunk but i have never required it and i doubt i ever will. What ever fills your sails. Cheers. 

Look in to "Breakerless SE" electronic conversion. Pertronix needs a full 12V to run, so you'll need to modify your wiring to your distributor to get 12V to it, and Pertronix also shows a 2nd wire.  Breakerless SE only uses the single wire as original from your coil. It'll look stock, and no wiring changes.

My points are two years old and need replacing and I will look at all options.

 Granted if you're looking to race the car, mileage & time might dictate a shorter interval of replacing them, but for everyone else, you might be astonished as to how little real maintenance points need - assuming of course your car is set up and running properly to begin with.

Yup.   Out of the blue, when a module fails, you can be stranded.

On a points-type setup, get a points file & also reset the gap and you are good to go. Not great, but good.

HEI is superior, but it isn't perfect. Like everything in life it is a compromise.
