Duraspark Box

What plug gaps is everyone running with their Duraspark Ignition?

I will be using a Pertronix Coil.

MSD says:"Compression Spark Plug Gap
Up to 10.5:1: 0.050" - 0.060"
10.5:1 - 13.0:1: 0.040" - 0.050"
Above 13.0:1: 0.035" - 0.045"

I gap mine at .050"
I'm running 10.5:1 CR and Bosch Platnum plugs. I have the Duraspark II and MSD Blaster coil with Ford Motorsport 8mm wires. Works okay for me.

I have been hearing quite a few stories lately of guys having trouble with their Duraspark modules.

I don't know what is fact or fiction.

You know? I don't remember what spark plug gap I'm using on Red who uses a Duraspark. For some reason I don't think it is as big as .050. More like .035.

Haven't heard any issues with these boxes. Red's been running strong for 3+ years.

I have mine at 0.050" with the Duraspark box, Duraspark dizzy, Bosch Platinum plugs, and Ford Racing 9mm plug wires

Thanks,

Ill give .035 a shot and see how it likes it and work my way up.
