hi guys
i decided to check how my wires were holding up at night. almost every
spark plug boot i know is arching, about 3 months ago, i installed autolites 25 gapped at 54 but then dropped it to 45, ford racing 9mm wires, 14* timing. i have stock e7 heads


thanks
 
i cant return them back because i dont have the receipt. my runs fine but its still arcing. i heard that frrp wires are known for this and people dont realize it it. im probably looking at accel, taylor. i also gapped the plugs to 45. i had 54 before but at around 4000rpms, it breaks up instantly.

btw i have autolites 25

That's because of the arcing. Replace the wires and regap plugs to spec. Also, when regapping plugs inspect for damage, fouling, etc. If they are suspect replace with copper core ones.
 
thanks for the replies

well the thing wtith fordracing wires is that they tend to arc within a few miles plus in addition i have my timing at 14*. basically they dont hold the extra spark resistance very well. MSD wires are very well suited for this. the car runs smooth at 45.
 
well i bought a over the counter set at autozone for now until i can get an msd set. runs good, i feel no miss but today i took a closer look, some of the wires where the boot is still arcing. not as bad as before though. i didnt put deletric grease on before i installed them. 1 of my friends, which is an engineer, told me to ground an 8guage wire from the head to the chasis so electric can flow. checked the rotor,coil, cap, everthing is fine.
 
I've had this for God knows how long. My ford wires did it, so did my msd, and so do my taylor wires. Mine doesn't hesitate or miss and runs smooth. I have an 8 or 10 gauge wire running from my coil bracket to a strut tower bolt. Nothing has changed and it's been 4 yrs. BTW I hated the msd wires, they "huge" the spark plug to good and I ended up ripping 3 or 4 of the terminals.
