dual point dist

[fordman]

would a dual point dist do anything fo rmy fe? i found aftermarket that fits an fe. is it worth using for my 390?

i have a origanal dual point in my 390 with a mecanical advance runs great but switching to electronic way more reliable and better fuel milage

I put in an Accel Points eliminator kit and now I recurved my Dizzy. I get better mileage and no points to replace. 48,000 miles later.

back when........... um.
well anyway, the big gain for most of us was that we could run a hot 12 coil and true 12v to the points and have them last long enough to count.

There are performance gains to have from dual points, but to be honest, the aftermarket electronic and eliminator kits offer as much or more with a measure more of reliability IMO.

If it's a C3 dist, it's worth something to someone restoring becuse it's a centrifugal advance 427 dual-point dist. Outdated, performance-wise. I have one in my 390 Mustang; works great, whatever the factory curve is...

Originally, Mallory made most dual point distributors with a single purpose in mind. That was to facilitate HIGH rpms without point "float" which was a common problem and operating characteristic of the single point set-ups. Dual point distributors also increase the length of time spark is present and also made for a stronger spark.

As an example, if you have a 360 that only likes to rev up to about 4200 rpms, you wouldn't gain any in most cases by going to a dual point distributor alone. If you had the AIR and Fuel systems modified along with the valve train and your engine was then capable of say 6500 rpms, you gain would be quite a bit. The dual point distributor would allow the engine to turn up to 6500 without "floating" the single point set, (misfiring), and would run clean and strong. You might be able to force 5000 from a good 360 FE under normal stock conditions, (downhill in second or third gear), and you would be able to no worry about losing spark because your dual point distributor would function probably to 7000 or more. This is where you would get the advantage.

If the money is right for the dual point distributor and you want more rpms and think your engine will turn up more, install it and enjoy. There are considerable advantages over the stock single point distributor. One step higher is the way to look at it. Then, the electronics, etc. are better yet. Get it and see if it is better in your own particular case. You can always sell it because someone out there wants that type also for many reasons. Good Luck!
