My Backdraft had about 4k miles when I purchased it...I have never found out who built the engine, a 418 stroker but it had Ford Racing plug wires, 8.5 on it. They looked like a snake that swallowed twenty chicken eggs. Too much heat and too close to the headers. They also had aluminum heat shields on the plugs which I removed...I replaced the wires with Ford Racing 8.5 wires from summit.
Have about 6k on the car now and so far no heat or distortion of the wires. I check them constantly and figure I'll have to replace them in a few thousand miles...I'm sure Summit will have some suggestions for replacements. Those guys know their business and are excellent to work with.
