Stainless Steel Wire Looms

[Tony, NY]

What is the likelihood of having arcing problems using these looms? Thanks.

Wouldn't you normally have the wires extending out of the loom by a few inches which would eliminate any chance of the loom arcing out? kind of like this...

I have used them on my 39 for over 25 years without issue. On my 32, I also chromed the original tubes. No problems

I had them on a flathead which I ran for about 3 years. Never had a problem.

Having plug wires running through any type of steel wire loom requires good insulation on the wires or you can/will have arcing to ground and cross fire between wires in the same loom. The key is having wires with good insulation.

I think the key is what's inside the insulation. Spiral wound is the hot shoe I believe. Though I won't be surprised if I'm behind the times on this. Not really about shorting out. It's all about induction, the ability for your spark to start running down one lead and then sodding of to the next lead that easyer for it to spark from. Compression makes it harder to spark. So next lead ain't got all that compression at the end of it, so it sparks here. The worst setup for this is solid copper leads that travel along nice and tidy bunched together. Sound familiar? In this respect I think the stainless ones you mentioned are probably a little bit better than the stock flathead ones.
I seen the power go up a tickle on a dyno, when the leads were pulled away from each other.
Also on small block Ford engines, if you seperate the back two leads on the drivers side (if my memory is working) with the engine idling, you can hear the rpm go up, and see a tad more vacuum on a gauge, with solid copper and cheap carbon string resistance leads.
That's the theory, In practice these little old flatheads spuddle along nicely thank you very much, with there stock set up, and will do the same with these shiny ones.
Ideal? Not really.
induction miss fire? Probably a wee bit.
Look good? Your opinion.

Trying to sort out a running issue. I have those looms and using these type wires. http://www.macsautoparts.com/ford_me...passenger.html
I'll check it out tonight when it's dark for any glowing or arcing. Thanks.

Just checked it out. Nothing visible. Even misted with a spray bottle. On to the next thing.

If you had an induction type misfire, would you be able to see it?
Genuin question, if it was arcing or shorting to a near by ground, you'd see it I guess, but with the induction cross over miss fire, would that be visible? As I said earlier, sometimes you can hear the rpm change if you seperate the leads. You can't do that if there running through some type of loom.
Any ideas?
