I have a shop manual but didnt see anything about the cylinders to check where is that located?

So starting with those and working up is a good start i assume, also just moving the distributor around till the timing seems like is probably a good move as well i assume, thanks again
I can attest to the hint about running the car in the dark and watch for sparking. My olds was running strange once and I did that and wow, what a light show I had going on under the hood. Runs much better now with new wires that aren't cross firing.

I would get a set that you can make your own length wires instead of the premade. They come out much better, you will find you can keep them from being on each other when you run them and make the lengths exact.

I can't remember if the straight ends or elbows work better on the FE's. The set my 58 had on it when I got it were so over long a few of the runs went over and were laying on the inner fenders . They were brand new so I just cut them all to length.

I also picked up a couple packs of the cheap plastic spark plug wire separators and used them where ever I needed to try and keep the wires apart.

The diaphragm is screwed to the breaker plate. It is the piece your vacuum hose plugs into and it is screwed to the side of your distributor. It is probably called a, Vacuum Advance Diaphragm. Pull a vacuum on the hose and see if the points plate moves inside your distributor.

Look in the "Tune-up" section of your manual. It will give the correct firing order. Also, read the section regarding the distributor, and how it is oriented.

Yes, always use good wires and a good distributor cap. Good wires are expensive but they are worth every cent. The original-type wires are ok, but silicone spark plug wires are a lot better.

The 390 engine is a very popular engine. You can easily find parts for it in any auto parts store. Put fresh spark plugs in, too.
