  Rotor phasing is an issue with a distributor. If you look at the spark tables in a DIS vs Distributor setup you can see the limitations. At no load cruise you want a lot of adavance and at WOT high rpms you want very little to none. Just the physical design of the distributor cap prevents major changes from no advance to full advance or the spark will jump to the previous tower.

Yes the functions are the same. However the connector has more pins (5 to 8) on a DIS module and the wires are in a different order. But hey, that never stopped anyone here before has it?
  For the message board: Has anyone out there done a sucessful dis to distributor conversion and had the engine run REALLY well after changing the spark tables to match the distributor setup? I've yet to hear or find anything. In thoery it should work but Murphey loves to attack non oem stuff.
