The resistance is about half as much on the Autolite resistor. That would seem to indicate there is also a difference in the coil impedances.

If that is the case, then with all else equal if the Autolite resistor was used with a Delco coil, it would stand to reason that less resistance in supply to a coil designed to need more would result in increased current thru the points which might tend to wear or burn faster. Conversely, if a Delco resistor were used with an Autolite coil the increased resistance might be enough to drop the coil voltage to a level that might not fire the plugs reliably under some conditions.

What is interesting is there seems to be no standard for "Universal" as Max seems to be supplying in the aftermarket. One calls his .8 ohm universal and another mfg calls his 1.6 ohm universal. If Max has had no issues reported, then interesting and there must be a wide latitude the coils can handle.
