A lot of old timer's in the sport claim that equal length spark plug wires do make a difference in performance. I can't see it. Opinions? Any dyno tuners out there ever test this?
How fast does electricity travel?
The timing difference between wires spanning an additional foot, short to long is insignificant.

...so are expensive 8 or 8.5 mm wires necessary or are standard auto parts store 7 mm adequate as long as they are in good shape with no leaks?

About 300,000 kilometers per second. (or 671 million MPH)
I'm not going to even bother to figure out how long it takes to travel a foot.
Ok, it's 1.1 nanoseconds (called a "Lightfoot") and is how fast light travels one foot of distance. (electricity and light travel at real close to the same speed.)
To put the answer of time difference in traveling an extra foot assuming 186,000miles/sec
.000000001 seconds.

The value of the "speed of light" that everyone is kicking around is for the speed of light in a vacuum -- that is not the same thing as the speed of an electron in a metal wire. But the point is the same -- it's way too fast to worry about the differential lengths of spark plug wires.
