Hei conversion troubleshooting

Yes, it is very hard to get on and off. excellent connection


No tach, the signal wire has a wire nut on the end and hangs down under the distributor.

So tomorrow, I'm going to mock the HEI back up with a new coil and module and see what happens.
I'm still a little hung up on the W/G orange and black wires and how that connection can supposedly be reversed. If it is an oem mopar distributor, wouldn't the car not run right with the original distributor connector and factory wiring harness? They only hook up one way, no way to reverse it.

As you can see in the above picture of my module mount, I currently have orange hooked to W, and black hooked to G. Again, car starts and idles beautifully. If i try to reverse them, the car won't start and backfires occasionally. So that should confirm they are in the correct position, right?

.............eh not exactly..........

There has been "some history" of rotor phase problems because someone offers modified Mopar reluctors. I don't know whether they are hype or not. BUT I DO know that "back in the day" once in awhile you'd run across severe cap tracking which I now realize IS one indication of rotor phase misalignment. To put this another way, "something mechanical" wrong in the distributor. Until you actually check this as I've suggested, you won't know.

Also there is at least one case on record where a Mopar pickup was color coded wrong. Now, maybe some body installed the magnet backwards. Maybe it somehow became reversed.

The thing is, you have big trouble here, and can not make assumptions.
