It's all about on how you set them up. I have ran a stock single point Distributor that has been curved with no issues. I now run a older Axcel duel point with a Super coil on my van (340) with no issues. My 69 340 Swinger has a Prestolite duel point (stock) with no issues. I just did the first tune up sense installing the 340 in 87' (around 65,000 miles) and the points looked the same as the day I installed them, but the rubbing block was a little thin as for why I changed them out. I hope the new set and condenser will be as good. Go back to my first sentence, it's all on how you set them up. I always set the points with the distributor out of the engine and if the dwell is off a little, I again remove the distributor and do the adjustment. The electronic ignition is not "FAIL SAFE" you still need to adjust the Air Gap. The modular and or control box can also fail without warning. Note: Never had an electronic ignition so I can not tell you which is best but I am content with the points set up. My 340's are mostly stock but I would think at a higher RPM the electronic set up would be better, though the duel points is better on the bounce than the single points.
