Correct length spark plug wires

I know this won't contribute to performance, but now that I've seen cleanly routed spark plug wires, I want the same for my Bronco. Are there plug wires that are made at a specific length to match firing order/Cyl location? I have some Ford Racing plug wires and it looks like a spaghetti mess, I've organized them as nicely as possible, but I'm wondering if there is something better out there, or do I need to go the extra step and make custom length plug wires? The picture of wire routing in the black mustang engine bay is what I want to achieve. What i have now looks more like whats in this red mustang engine bay

I've had luck with the Motorsport wires laying out very nicely on several projects.

Motorsport wires lay better than most. If you have an HEI they probably won’t be quite as clean as what you sent. The absolute best would be to buy a set of build your own wires from Taylor. The plug end comes pre installed so you can set them in the separators and run them however you see best to the distributor. Then you just cut and crimp. I usually mark the top of the wire so when I crimp the end on I don’t end up with a twist.

Yeah, I think part of it is for sure the HEI making them look ugly, but some of the lengths on my ford racing 8mm wires are like 3-4 inches too long. Since they're numbered, thats why I was thinking maybe they were made for a slightly longer length to go to a different location on the distributor cap for another firing order

Didn't Ford Motorsports have a set of universal cut to length plug wires at one time? I may be dating myself from when they were 8mm wires instead of 9mm.

Yup they did bowsher!

Ditch the #dizzy as Garry was always posting!

I went to a lot of effort to not have a distributor for performance and reliability reasons. Haven't looked back or missed that big fugly looking mess in 14 yrs or so. :)

You probably already know this, but since some are too long for your liking pull the wire and clip out of the boot. Then open up the clip carefully, shorten the wire, re-clamp the clip, and slip back in the boot.

HEI definitely makes it more difficult since you can't easily run wires right over the distributor. 90 degree boots help a lot when they can be used at the cap.

I have Ford Racing but the #2 is short for the routing clamps I use to clean up the look. Some time in the future I'm going to pull the dizzy and rotate it to see I can get it to work,

i was always under the impression that a perfectly clean run is always custom cut. They have kits that you cut to length and crimp... been thinking of doing mine but they aren't too messy.

Years ago, some parts houses sold individual wires in various lengths. I would go in with a list of what I wanted for a tidy look, and could pick and choose what I needed. Generally I could find something plus or minus an inch of ideal for each wire. I haven't seen those individual wires sold anywhere for years.

+1 on making your own and route them how you want.

I used MSD wires and a the Titan crimper I have with a die for that but a lot of crimpers available. It's not that hard if you do it right and test wire resistance when done.

When I worked on dynos we mostly ran MSD spark-plug wires, but one engine didn't respond well to them as we were still getting noise in the D/A system that was messing with the values. Even with the previous engines there was always a little noise. One of my fellow engineers did some in-depth research and found these wires: https://magnecorusa.com/ We made a set from their std. 8.5mm wire and ALL of the noise in the D/A system disappeared. From then on those wires were the only wires that we used.

I used my own MSD crimper/cutter to make those wires.
