Ford FE 390, 427 and 428 Firing Order
Well it actually is the same for all ford FE's, this included the 352, 360, 390, 406, 427 and 428 engines. When I think of the Ford 'FE' ironically I think of Iron (no pun intended... well a little). Here is a nice LARGE EZ to read firing order that can be printed for your shop or viewed on the phone while trying to figure out which plug wire goes where!
These are a large heavy motor that found it's way in to some of Ford's lager sedans and trucks, and oh, the Shelby Cobra. I have some limited experience with this engine, replace an intake, moved around a 390 on other occasions, and all I ever thought about was 'this $hit' is heavy. Pulling the Iron intake manifold off of a 390 in a wagon made me understand the Ford shop manual that said 'Use Crane to Remove Manifold'. Also it was interesting how the intake manifold splits into part of the head. Just didn't look right. Hey, for Big Blocks I'm a Chevy man sorry. And just want to not take away from the durability of these engines, but not my cup o' tea. But don't think for a second I wouldn't take a 427 Galaxie or Fairlane, those are Bad A$$ cars.
Also remember that the position of the spark plug wires does not matter AS LONG AS THE ORDER IS MAINTAINED! If you need to rotate the cap for any reason don't worry about pulling the wires and rotating them around. Again this is OK as long as the firing order for the engine is maintained and you check your engines timing.
So if you want to cut and past the Firing Order for the FE Ford's (352, 360, 390, 406, 427 and the 428) it is :
1-5-4-2-6-3-7-8 (Same as old school 260, 289, 302)
