Firing Order Ford FE390 - need help !

[DesertMK4]

The firing order is determined by the cam not the block (small or large). HO Ford engines (usually 302s) have their own firing order. The cap makes no difference in the firing order, unless it only has seven leads.

That is soo true. All ford distributors from 57-73 use the same cap with just #1 molded on. Firing order is determined by the cam.

Well, it might improperly - if the cap has a SB firing order molded into it (as the OP said his has) and someone not knowing any better tries to wire his FE to match it. I don't see where anyone alleged that the engine's proper firing order is established by the cap.

You did.

There is no small block specific dist.cap. They are all the same. The op never said the firing order was molded into the cap. He said it was marked. I would think most likely with a sharpie. Anyway, I think we've sufficiently covered this.
