Blown 440 spark plug gap
I ran an Accel dual point and Super coil on my blown Rat motor 475 cu in, 21% overdrive on an 871 blower. I never gapped my plugs special, .032 or .035 as I remember. This was in a pickel fork jet boat. Ran and beat the hell out of it on the Mississippi River every weekend. I will still say that no special gap needed. On my airplane with an old magneto set up, .018 plug gap. Electronics are better.
