Charlie,

I have a flattop Mallory for an Olds Rocket that has a four lobe cam. The points are not wired together, each set having it's own terminal on the side of the distributor housing. This distributor uses a special Mallory coil that has two primary windings and one secondary winding. Each set of points energizes it's primary winding alternately. It's sort of a "poor man's" dual coil setup that doesn't require a special cap or rotor. I also have a couple of SBC flattop Mallorys with 4 lobe cams where the points are wired together and feed one primary on the coil like regular dual point. I believe these are called "Double Life" distributors because they alternatively fire each set of points to energize the primary, resulting in half the wear on the points. I believe this type of distributor needs the 180 degree plate. while the first requires the 135 degree plate. These "poor man's" dual coil setups obviously require two condensers.
