big block burning plug wires

this a 69 Dart...the 76 Duster is slightly different and I have no lean condition, if anything I am running rich
Sorry you are having these issues, like another member posted maybe you are running lean, I am using tti's, 2 inch primaries ceramic coated and have NEVER had an issue in my 76 Duster.

NICE FIND,Roy.... I
interesting Roy but the widest part of these Rajah plug ends wont burn also??? they look awful wide to me, so wide they would touch somewhere on the header and I would be back go square 1... so these just install in the end of the plug and the plug wire then onto them...I also saw the taylor wires and talked with them, they told me that if their ceramic wires touch a header ANYWHERE I would be back to where I am now...
