Spark plug gap with electronic ignition

[duayla]

I have an 82 A/S with a 351. I put a mallory electronic ignition in and ready to replace the spark plugs. Does anyone know if the plug gap should be increased from .032"?

Use Autolites 24 or NGK BPR6FS plugs. Gap should be .035.

hotter spark can easily get away with wider gaps

Commander Fords either .032" or .035"

PCM Ford and Chevy with convention old school ignitions call for .035"

the electronic ignition you doesn't make the spark any hotter than the coil installed can provide
but it will pass close to full coil voltage now because of the better switching compared to the points

I set my points boats to .035", electronic conversions to .040", new chevys w/ EST to .045"

good luck
