Timing

Hello group, would changing the plugs and wires in my 79 F-250 , 460 change the timing?
TIA

no, assuming the distributor didn't get moved, and the wires were all put back in the same order.

Why do you ask?
What is happening now that did not before?

No. but you should check your curve with a dial back if you haven't already.

Seems to have a slight miss. Wires were put on as they were taken off. According to the manual picture, where the pen is pointing, I assume is the cap clip. If you look at the actual picture of my setup, those clips are not in the same spot.

It makes no difference what terminal you start on , as long as you pick a #1 and start there with the firing order in rotation.

The #1 position in the manual is just the standard positioning. if you'd rather have it that way just move every plug wire on the cap a hole.

Your timing is more important, you should check it .

How does one verify a miss isnt from a bad wire? short of feeling every inch of cable while its running, lol? mine look new but are only 7mm
My 360 has a pass ex man leak so its hard to tell if the ticking is from that or snapping from bad wire.
is above firing order same for 360 FE/390FE? the pen is covering it...
right now im assuming my miss is probly cuz of weak compression on #4 clyinder. but u never know.

I've always pulled plug wires one at a time to listen for changes/additional misses. Once you find which cylinder(s) are missing, then you can swap wires/plugs between cylinders to isolate the problem. If the problem is internal to a cylinder, the problem will remain at that cylinder regardless of wire/plug swap.

Look at it in the dark running, you shouldn't pull wires off a running duraspark, it can damage the electronic. If you have a pacemaker if could kill you.

FUNNY enough, my engine seems to have dist cap clocked exactly like this Ford manual.
is this perhaps the ideal way to orient i to have the wires set up neatest and loom together neatly aound all the obstacles?

cuz i tried it with #1 pointing at number 1 and best you can get is 2 crossovers and a wire on each side wont be neatly fitting into 4 wire loom /holders.

Hinda hate to ask this question but,
Did you check the gap on all the new plugs before installing them.
Reason for asking;
I have been around some guys that just open the box and stick in the plug.
I ask them why they dont check gap and the answer is always ( they are pre set from factory)
Of course my statement is yea they are pre set UNTIL the box gets slamed or droped on the wrong end...
Just asking.....

Don't let 7 and 8 cross each other. Induction misfire.
