Well done plug wires

[Pete]

Howdy. I have a 1974 with a 440. keep roasting plug wires. Some due to movement, but some due to heat from the headers. Have insulated boots, but can anyone recommend a good heat resistant plug wire?

Might need to get a plug wire heat shield to run them in. Or try to see if they have a fiber glass sock to go over them. Try summit racing or Jegs.

Thermo Tec Plug wire sleeves. Summit racing.

Yes and they did not have this kind of stuff back in the day. Our 440 with headers was really bad about the back plug wire's being over heated.

 

[Pete]

Yeah, the third one to the back, passenger side has the header wrapped around the plug.
