Hy,

I French, my name is Florent and I'm assembling an engine which uses a gray TFI module from a 1964-1973 Mustang. So I search what coil I can use.
I would like to use a Pertronix coil with a 0.6 ohm primary resistor or a msd blaster 2 but don't they have too low primaries resistance? What is the maximal current that the TFI can produce safelyto the coil?

Thank you very much for your answers. And sorry I'm difficult to understand.

Nobody?

Do you know a web site where I can find the characteristics of the TFI-IV module? Iwenton the Motorcraft website butI've found nothing.

Thank you,

FLorent

 

Sorry, the TFI module come frome a 1987-1993 Mustang.

Get the MSD coil designed for the 86-93 Mustang and you will be fine. You have converted over to fuel injection I assume?
