SPARK PLUG WIRES?

SPARK PLUG WIRES?
I'm looking to clean up my engine a bit. I'm currently running MSD 7mm Wires and they seem to just be all over the place. I'm trying to find some wires that are much shorter in length. If you guys have any links that would help me out, or suggestions it would be great. Also with my set up can I go to a larger gauge wire?
Thanks
(I have a 67 289 with a pair of Headman Headers and a Mallory Dist.)

Get some of the cut-to-fit wires. You have to put one end on, but you can get them to the perfect length and really clean up the appearance of your engine. I'm guessing you could go to 8mm wires without issue.

I have been real happy with my ford racing 9mm wires from summit with my msd setup. heres a couple of pics. They are made to fit by ford they are numbered and look nice. http://store.summitracing.com/

I hate my Ford Racing wires, but then I'm running a different loom setup than mustanglover. No offense, but I don't like that particular style due tocrossfiring issues with the #7 and 8 wires. I'm using the Ford Racing looms that stick up from the top center valve cover bolts, and the wires are not designed for them. The #1 and 5 wires are way too short, and the #4 and 8 wires are way too long. You'd think everything being Ford Racing, it would all fit...
Next time I'm going with some blue Moroso cut-to-fit wires.

I found these, they are like yours but cut to fit from sumit. What do you think?

those should work they are the same as the ones i have but cut to fit. And Starfury I know what you mean by cross fire i was seting my timing once and put my hand on top of the disturbutur. to turn it and got the shock of my life.

That's not what I was talking about.... If that really happened, you need to check your connections and even the wire resistances. The spark shouldn't jump to your hand assuming all the connections are good. If you need to, use some dielectric grease on all the wire contacts.
What I'm referring to is inductive crossfiring between the #7 and 8 wires.The standard firing order is 15426378. As the #7 plug fires, the #8 piston is almost halfway up the cylinder, the absolute worst possible place for a spark. If the two wires are too close to eachother and not shielded enough you can get an inductive kick in the #8 wire which can fire off the plug, causing extremely premature ignition. As pressure increases due to bothcombustion andthe piston rising, the mixture eventually explodes all at once (aka detonation) long before the piston reaches TDC. The resulting detonation combined with the force of the piston still trying to move up can cause severe engine damage, especially if it's repeated several times.
Moral of the story: keep the #7 and #8 wires as far apart as possible.
