What's the firing order of '89 460cid in a F350?

 

15426378

Same as all the other 429/460's

 

and number 1 cylinder is the front passenger side correct?

 

Yep!

And the distrib on mine (85) runs counter-clockwise

 

I hear Ford numbers the cylinder 1234 down the passenger side (front to rear)
and then 5678 down the driver's side front to rear.

 

that is correct

 

The firing order is cast into the driver's side of the upper plenum of the EFI engines.

 

1-5-4-2-6-3-7-8

 

I changed the plug wires on my 460 and I think I might have mixed them up.can anyone tell me what order the wires go on the cap?

 

tfb4me,

The firing order means the order "the wires go on the cap". You start with plug wire for cylinder # 1, then go to #5 and so on. Counterclockwise unlike Chevy.

That's easy, the only thing to watch out for, your #1 has to be where it was before. It's called TDC - Top Dead Center.
