metal spark plug wire looms?

I've seen Flathead spark plug wire looms made from chromed tubing. Does this cause cross-firing or interference? Could I make my own set from fuel tubing?


Thanks,

I would think that it is usually made from stainless tubing. If there is crossfiring or interference, it would be from lack of insulation on the wires.

 

The olde speed equipment looms were made of plain steel plated with that wonderful JC Whitney grade chrome you could rub off with your fingers after two weeks...
And of course stock flatheads used a single big tube on each side from '32-48.
Not good in theory, but I've never had any trouble with stock flathead ones.
Use good quality wire, be careful with wire at ends of tubes (Maybe flare tube a bit, too), stick close to stock plug gaps. Any excess of resistance in ignition of course sends the electricity looking for an easier path, but with everything in good condition there's no great worry.
In a traditional ignition, voltage is determined by the resistance of the plug gap if all else is properly insulated; with electronics acting like CD, the ignition can have higher energy than that required by plugs, and that might mean trouble with metal close to wires.

 

This is a year old, but did the looms ever get made?

Badger was a name brand that made the tubular looms

 

I made mine from brake line. Flared ends keep the chafing away. Chrome keeps the rust away. The whole thing keeps the packrats away
