I searched the web to find the application for these two part numbers and they both appear to be for Chrysler 6 cylinder and V8's, 1962 - 72, but there is a difference in spring tension. When would you choose one over the other?

Thanks,
David

More pressure for higher RPM, but I wouldn't use a point distributer in todays world unless it was for a "show car" that require the OEM distributor for judging

Nothing wrong with points setup, if you don't mind the added maintenance. But quality time with your ride is relaxing. My daily driver is a points car.

Problem is, though, modern made points suxk. The rubbing block wears out fast. So you are stuck finding NOS stuff and that might be a good reason to convert.

V6 62 - 72 ?????
Hard to find , if you need them by them both , as sniper mentioned , new stuff sucks compared to the old.

I assume the 'V' means vented points. That is a good thing for temp and overall life. But also means slightly less surface area to contact. When you get the points, check to make sure that the contact areas are square to each other. Fairly often, even back then, the mating surfaces would not be in good alignment which means a smaller contact area, which would speed up the maintenance cycle. We always used Sorensen ignition parts back then. They actually had cross vented points. They were the longest lasting points I have ever seen. But that was a long, long time ago and I am not even sure Sorensen is around any more. Let alone being the same quality even if they were.

If you don't need the extra spring tension for higher RPM stability, the lighter spring will usually require less frequent adjustment due to less pressure on the rubbing block.

Back in the day, if everything was in spec, it was typical to go well over 10,000 miles before an adjustment was needed on daily driver stuff. And given an occasional check with a dwell meter, I have seen 15,000 miles between adjustments. Or do like most did back then, wait until it starts acting up before you pop the hood to see what's going on.

V6?? fits all mopars 1961-1972 single point distributor , higher spring tension for high rpm use

Oops! Didn't mean to put V6. I edited that part of my post. Should read 6 cylinder.

But it can't be for all as your edit shows , small block and big block points are different, ... don't know about /6 .... , rotation of the distributor is different so you can't interchange . Make sure you get the right ones for your engine application.

Not true for Single point. Parts book calls out the same single point contact set regardless of engine type. Dual Points are different.

Ok , my bad I was thinking dual point because my 383 Dart has dual point ... carry on
