I need to double check the firing order of a 392 Hemi. Does it fall into this generalization? And is the location of number one on the distributor correct for a 392? ![]()  |

This one is for a '55 Chrysler 331 Hemi...  I believe that they would be the same. |

Everything looks kind of the same except the distributors rotate in reverse.

I think you're right Steve. Looks as if the 392 had the same common firing order as most Mopar and GM cars, but the distributor rotation was counter clockwise and the number one firing position is on the left side of the distributor.

One big difference is that the distributor is in the back on a 392, and in the front on the 426.

The distributor rotation was the big thing. If I'm going to the trouble to wire the thing I'm going to wire it in order and the rotation makes a big difference.

The image I sent is the most accurate because it is for the early Hemi with the distributor on the back of the engine. IMHO

The image I found and the one Steve had appear to be for newer MOPAR big blocks like the 426. When it comes right down to it, not many people would notice if I had this wired wrong. Considering no one will ever open the hood and look at the motor once I'm done with the build, I wouldn't even need to use a wired distributor. I've decided to do it for me, and since I'm doing it I might as well try and get it right. It's not that much extra trouble to get it right, especially with all you guys to lend assistance. Thanks to all! |

I try to get the firing order in the right sequence, too, even on non MOPAR builds.

I remember, back when I was building before, having to stop myself from getting to carried away with super detailing. I knew I'd gone over the edge when I started looking for a bit of wire that was the right color for the stripe on a wire, then painting the wire the color it was supposed to be and using an Exacto knife to expose the stripe color. I would do this for any wiring that could be seen, like the short bit of wire that goes to the headlight coming out of the wiring harness. Looking back it took a lot of the fun out of building for me, but it was extremely soothing to my CDO (CDO=OCD with the letters in the right order, DAMN IT![LOL]).
But I still can't help trying to get the firing order right, even if no one will ever notice. LOL
