Spark gap with MSD ignition.
I put an MSD 6a ignition with their blaster coil in my 95 300/6 and am curious as to what kind of plug gap i should run, what you guys have had good luck with? Also, i'm wondering what kind of plugs you guys are running in your 300/6s, should i just stick with motorcraft? I think i have champions in there now. Thanks in advance.

I've never had any experiance with any sort of "fancy" plug that would come close to making them worth their money. Just an expensive gimmick. I just run plain Autolites. Sorry, cant tell you about the gap... MSD should have the specs. Please post your impressions of the 6A when you get done though!

221, since you have the Blaster coil, you can gap at .055", then if mis-fires occur, drop the gap down to .050".
All of the Blasters put out about 45K volts, so I wouldn't go above .055", at any rate. I am also a firm believer in low resistance sparkplug wires. A set of these will allow more usable voltage to reach the plugs.
