There is a bit more to the story.
If you use a pertronix type system, you need to time it once. The only problem with the pertronix unit is it retains the old mechanical spark advance system. If you choose to install this system, check out the mech advance mech for sticking/wear.
If you install a HEI type unit, it's all in the control unit. A YLM dist is recommended by some. Not sure if they make a 4 cyl model.
