Your engine should have the early Duraspark ignition, so should be a one wire hook up. You can get the brain box from NAPA and an electronic coil to suit it, there also.The Duraspark II will need two wires hooked up to make it work.
The Duraspark ignition is about as good as you can get, without having to spend a lot of money. It is reliable and parts are cheap for it. To hook up the early Duraspark, first, what you need to do, is make sure the brain box is well grounded. Next, you will notice that there are two pigtails coming out of the brain box. One will have three or more wires and the other one will have just two wires. The pigtail with the most wires connects to the distributor pig tail. The other one has a red and a white wire. The white wire should be connected to the hot side of the coil. The red wire doesn't get connected to anything. Some guys run a ballast resistor in the line to the distributor, but I never did and had no problems.
With the ignition wired up this way, it should fire up on the first try. I used a Mallory dual point distributor on my first V6 Alpine, but they were a pain to change points and set them. It was easier to just remove the distributor, replace the points, set them, then replace the distributor and set the timing again. The electronic ignition doesn't have the points and the plugs will last a lot longer ( 8,000 miles versus 30,000 miles).
