We went from a Mallory dual point to a MP Elect Ignition and the times didn't change much but was a lot more reliable. We didn't have to deal with the points after every run (exagerated of course). Sure beat dealing with burned points. We ran the 440 with dual points for about 10 years then the MP Elect Ign for about 8 years without any problems and never needed to adjust except for timing of course. We always used the orange box.
