What are you doing with your truck? The Duraspark unit should be just fine for everything up to ~6000 rpm.
What is the Wells unit used for? Is it a distributor pickup? If it is an ignition module in it's own right it is not needed and is probably causing problems. The stock pickup unit should be used with the Duraspark.
An aftermarket ignition system will not be an improvement over a properly functioning stock system unless you are reving in the 5000+ range.

Well, the Wells unit is located on the driver's side fender well and has wires that come around and plug into the bottom of the dizzy and have leads to the coil, if i remember correctly the wires are green/black to coil and purple/orange to dist., i dont ever revv into 5000, actually im scared to, its a rebuilt 351M, but hell they didnt run that good. anyways, you are telling me that my factory coil that is 25 years old and dist base offer the same performance as did when it rolled off the dealership lot? if so that amazes me, but a new coil, dizzy and "wells" thingy box has to make a difference for daily d, they make a package by MSD for daily driven 351M/400 motors.

I have an old magazine (1987) that shows how to make a duraspark work up to 8000+ rpm. It was written by Dr. Jacobs (Jacobs Electronics) He used a throttle switch and a motorcycle battery and several relays to run 24 volts through the ign box at wide open. It was written for drag racers I guess. The article gives all the tech detials as how/why it works and a wiring diagram to build it at home.
