Spark plug wires and heat-resistant boots?

[pvoth1111]

I've had some spark plug wire issues on the big block, I have had to put a sleeve on  #8 to keep it from burning up.

I've put Napa blue wires on it and was looking at wires in my new Jegs Catalog.

These big blocks seem to be a bit harsh on wires....

What are the recommendations of the peanut gallery?

I got the MSD Super Conductor wires which had high temp insulationg boots and they were multi directional, which was really great, especially on the driver's side on a Dodge 440.  The fathest one back from the front on the passenger side was still tough though.  After 3 years, that boot had hardened from the heat and when I went to pull it off one time, it finally cracked in half.

However there are options available.  I'll let the gang get you up-to-speed on what they're using.

Are you running factory exhaust manifolds or headers?

I put sleeves on my dodge as well.

I have used spark plug insulating boots from Napa before with excellent results. had them on my '83 Chevy 383 stroker with Headman Headers for 7yrs and never burned a single boot.

They are sold in 2-packs.. you'd need 4 packs to do a V-8 if you insulate every boot. Call your local Napa Parts dealer to get current price/availability..

Hey All! Regarding heat resistant plug boots on 454 chevy with or without headers. I used to be a warehousing dealer for "JACOBS ELECTRONICS" I worked with Dr. Chris Jacobs (holder of over nine PH.d's in Electronics engineering) for a time in LA & helped develop CERAMIC plug boots. They will NOT burn out & are rebuildable. Number 8 being the worst offender. I've had mine for 6 years now & had only one give me trouble, number 8 you guessed it. I have replaced the wire with another & installed a heat boot over the part closest point to the header & no more problem. The initial cost seems like a lot but with the ceramic boots are forever & any unfinished wire set can be installed using the boots instead of the burners. Problem solved for me at least. Just my two cents C YA! GONMAD

Improper punctuation. The ceramic boots only protect the wires . The advance kit retimes the distributor. The retiming lowers ex temp and improves mileage  Not the wire insulators.  I use (with my headers on my 350) asbestos boots from Advance Auto parts have not had a problem in over 20 K Mi  Now with computor controlled ign the ex should be even cooler  Frank

I installed the ACCEL Extreme Heat 9000 BLACK Ferro-Spiral Spark Plug Wire Set....I have yet to drive em down the road at this point.
