HI ALLI would like to have some ideas for spark plug wires and routing on my 400. I am using the Duraspark 2 and have the tall Ford racing valve covers. What are you guys and gals using? The truck IS a street Queen driven in NICE weather, taken to truck shows, put away for the winter BUT will also be raced at a drag strip occasionaly. I have ALL the goodies inside and out. Any suggestions? Also what do you think of the E3 plugs? Are they worth the extra or no? I am using the stock heads. Popa John
