Help Junkyard coil for HEI distributor?

TrailBeast sure knows his stuff. I think Ford calls their ignition "TFI". Easiest to stay w/ that since you have a nicely wired connector. For others, the GM HEI "external coil" (85-95 V-8 ) is nice and gives a tach output wire. You could even use a Mopar Magnum coil (92-00?) if totally loyal. It bolts to the front of the engine.

Elaborate on how you determined "bad coil". Kit and I wonder since those look very rugged. But, I did have the similar e-core coil-pack in my 2002 3.8L Chrysler fail. I got no flashing with a clamp-on timing light over the 2 plug wires of the coil closest to the engine (hottest) and could hear a faint clicking inside. A new one fixed that.
