Spark plug wire size

[V8tiger]

I'm working on the engine of my 1/16th scale "Green Elephant" funny car. What size spark plug wire should I use? Thanks to all...Joe

Something in the .015" - .020"  (about .4 - .5mm) should look right.

That depends on what plug wire diameter they used in the early 70s funny cars and dragsters.... Was it 6mm, 7mm or 8mm plug wires???..?

Just take those^^^^diameters and divide by 16.... The scale your working with and you'll have your answers...

Correct! I was assuming Accel or Mallory 7mm wires as a common standard for race cars in the 70s. I think 8mm wasn't common until a decade later, and no serious racer would have been running 6mmm at that time, UNLESS they were the old solid core wires! ( I used to have a set of those hanging in the shed, finally tossed them; solid copper core in translucent red jacket.) Was the Green Elephant a real race car? You might have to do a little research there...
