What Ignition Wires to use on Big Block with Headers ?
Permalink  

Looking for recommendations on ignition wires to run on my 454 with non HEI distributor. I transfered my small blockset for now to get the engine running but know that I need straight boots to clear the headers. 

I am not a fan of coloured wires so prefer grey or black, similar to OEM look. Original style AC Delco 508R are available from my local dealer for $60 but I am not sure how they will fair vs. headers. 

Suggestions please.

I'm afraid you'll likely have to go coloured Ray. Those original black wires will die a horrible death in short order with headers. I'm with you on the coloured wires but I put orange silicone on my 65 and it only has manifolds. Those black wires are good for shows...

I am using Taylor Thunder Volt 8.2mm wires on my big block with headers. They are universal so you have to put the cap end boots on. They have a 135 degree boot and I have no problems with them at all. They are black with gold lettering.
 When I was cruising Woodward this past summer the car got really hot but had no effect on the wires.

 The part number is 83053 if you are interested.

 I also have a new set of GM spark plug heat shields if you are going to use them.

Thanks for info and offer Brad.

What is the consensus about using shields, I know they are used in a lot of GMC applications.

 I made my Acadian set. It's sure nice. You can tuck them in where they belong.

 Yes, I do that as well... Alot of times here in the shop when you pull the end out of a wire pulling it off the plug, I just reattach...

 I use to save the original wires off of the trucks that had numbers printed on them wit the 90 degree boots. Then I would save wires from cars with the 3.8's that had 180 degree boots and transfer those onto the the truck wires with the numbers.

 I believe both of my EFI'ed '67's with the original rams horns, have numbered straight booted cut to length wires on them....

This is kind of a crappy pic.  Kind of the best view I had of them on my pc...Hope this helps. If you want a better pic I can take one tomarow.  MSD wires and the wire holder / loom kit is GM from the 502. There isnt a better way to hold your wires out there. Think it was about $20 for the wire holder thingy. Think the wires were in the $70 range but ive had them a long time.

That gives me a good idea, pretty much a look I would go for, thanks. My OEM chrome valve covers have built on looms.
