This is of great help.
I was certain that the 140 hp and 165 hp CFI's used in the Tbrid and LSC, #7 and Mustang HO autos was Duraspark 3, and basically the same electronically as the 120 hp plodder used 1979-1985 CFI full size Fords. I understand that Ford only made a few really small changes to what was an excellent and often misunderstood EEC3 engine, with it not even being updated to the later EEC4 format for 5 whole years.
Is the 5.0 HO Duraspark 3 a TFI igntion system, or have I got my wires crossed?
