Not sure of the term buts two spark wires firing next to each other causing an ark..
Is there two spark plug wires that should not run next to each other.

Also I learned the hard way on the block mounted spark plug brackets a stud and nut is much better then a bolt. Even then the stud is very hard to instal on the left side.  

Thanks,
Richard

Here’s the link to a previous post covering how the spark plug wiring should be routed.

Cylinders 1 & 2 on the right side and cylinders 6 & 8 on the left side are susceptible to induction firing if the spark plug wires for those particular cylinders are running parallel to each other.

Ford issued a service bulletin about the wires in the brackets.  I don't have it handy or else I would post it.
