Like some of the previous posters, I've had good luck with the Taylor spiral wound wires.

There's two reasons I'm not a big fan of the braid covered wires. The first is that the external braiding forms the equivalent of one plate of a large capacitor, and the plug wire internal conductor forms the other plate. This means that the ignition coil has to charge up a large capacitor to a high voltage before the plug can actually fire. This just slows up the high voltage ramp, allowing any sparkplug carbon fouling or deposits to leak away the coil energy during the high voltage ramp up, reducing the net energy delivered to the plug. Is this a problem? Usually not, but I'm not a big fan of things that reduce the efficiency of a component.
The second thing I'm not a big fan of with those wires is that if there is any marginal insulation anyplace in the length of the wire, the spark only has to take a short jump to ground out against the braid. Does this happen a lot? I don't think so, but again, I don't like stuff that increases my chances of having problems somewhere down the road.

Is that the same for a HEI Distributor?

blue by you

Yes it is

I have a new set of old wires not a current # are these any good?

I would contact Taylor and ask them the question. You will probably get the most direct and accurate answer from them. Be sure to include the part number on the package you have.

I have used the Taylor Spiral Core wires on a number of vehicles and been very pleased with the results. They are very easy to install and fit to the exact length you need. That way, you're not having to find some place to hide the extra length, which always seems to get in the way of the normal Corvette shielding.

Good luck... GUSTO

So did I. I needed the thicker MSD wires and put them into stainless overbraid, looks like original. Sure it´s thicker over all, but this will only be recognized by the experts.

What engine were they for?

I was planing on using them with my SB & point distributor (74) because it has a blower going on it and theirs not room for the shielding.I bought a lot of parts 20 some years ago and been digging them out as I get deeper in to it.

I have a 69- 390- 427 also Motor has some upgrades and MSD. I couldn t believe the diff. in performance when I changed the wires to 8mm accel. The braided wires were not old maybe 3 years and 2000 miles. I keep the braided in a box just to say I have them .Todays stuff is just way better

MikesRed68

So what are u saying ? U changed the braided wire to 8mm accel ? Todays wires are way better? Which wires are u reffering to? The braided or Accel 8mm

crisko

Yes changed to 8mm accel.As 69427 said the braided wires can cause problems which was my situation

MikesRed68

crisko. What were the problems you were having or had with the braided .

crisko

Bad idle caused by dirty plugs . Just wasn't running smooth . Started by changing out the wires and couldn t believe the difference. That was 3 years ago and haven't touched it since.

When the braided wires were installed on the 68 and 69 big blocks it was for noise suppression only, not performance. If you ordered a car with a radio you got braided wires and without a radio, normal wires. I have them on my stock 69 L36 and they look kind of cool but as far as performance they are probably more of a hindrance than anything else.

These are also 8mm

CanadaGrant ...Would u be able to tell or feel the performance difference?

MikesRed68

Ok i called up Summit Racing and spoke to a tech. I am or was ( still debating ) on Taylor Street Series Full Metal Jacket HEI Ignition wires. Model or Item # 91004 . They are about $180. And the tech told me these braided wires are high performance. And never ever heard of someone saying that they had a grounding issue or any other kind of problem with them. Maybe if u looked them up on Summit Racing u could tell me more about them. Like i said i do love the way braided spark plugs look and he did say that THESE ARE PERFORMANCE TOO. Also he said these are the same as the Spiral wound except braided and chrome plated boots for heat shielding. Check them out ok? Tell me what you think..

I sent Taylor an email yesterday but haven't heard back yet on these old wires.

MikesRed68

How much did u want for em?

CanadaGrant

No. I have never used a wire where you could actually feel the performance difference between sets unless the wires are bad or burnt. I think the difference between well made wires using top grade materials and cheap wires is not performance but reliability and length of service.
