Anyone running angled spark plug wires on a 454? (edited to reflect issue)

[TexasAggie]

Howdy folks -

I managed to burn up two spark plug wires on my 1999 K2500 Suburban with the L29 7.4. I installed headers last spring and put the little heat socks on the plugs that were closest to the headers on the passenger side. The first time I've towed with it was this past weekend and I guess two of the wires were resting on the header without me realizing it.

Anyone running angled plug wires in this situation?

I've done some cursory searching, but I don't see any with a straight disti end and angled plug end. Anyone have any leads?

I don't have any help for you in the parts search, but I put a spark plug boot protector on the one wire on WCJr that I couldn't find a happy place for. Also, use your spark plug wire holders to pull the wires where you need them to keep them off the headers.

I have those protectors already, but wasn’t paying attention and the wires were resting on the header. I’ll grab some new wires and holders and make sure everything has good clearance.

I usually keep my old wires for spares, but threw the old ones out a few years ago when I changed them. I only need 2!

 

[Erik the Awful]

You need eight, and now you'll have new spares.

Fair, but these only have about 8,000 miles. So I guess they'll make great spares!

I used these Accel 135 degree ceramic boots with 8mm wires with my custom headers, nothing else would work. For the dist ends, I took apart and modified oem 7mm wire parts, which did work but they will separate when I try to take them off some day. Taylor makes this set of 8mm wire to vortec/optispark dist boots, which I bought on ebay for $20.I will put them on eventually, just don't feel like it right now after the last 2 years of work..

The 8mm Ferro-Spiral core wire now has ceramic boots on the spark plug end of the wires. The ceramic boots will withstand up to 2,000 degrees F. The wire uses a 500 Ohms/ft Ferro-Spiral core developed for performance use.

I did a continuity test between the +12v pink common wire, C1-19 on the 0411, and each injector pin. It showed open circuit on all 4 of the left side injectors. It didn't run that rough, so it had to be an intermittent problem. Turns out it was a weak connection on the left bank common pin on...

Custom plugs here as well. They sell just the angled parts that you can modify your existing wires with.

Is that an 8.1?

That same worked over l29. Tall deck block and newer ecu swap.
