    Pretty self explanatory, but what plugs do people use with their MSD 44's?

    This will probably be another of those questions which will give plenty of variation as of which plugs to use. :)

    NGK R6061-10 or a cheaper R5671A-10. The 5671 has a longer groundstrap so if you are pushing the envelope you might have a problem. If not they work just fine. You can also use the longer groundstrap as a warning device if it gets nipped and you get a chance to back off. With the 6061 the groundstrap is real short and the piston will probably go about the same time as the groundstrap with no warning. I would gap both of them at .015-.019".

    The standard gap for a blown application always used to be .019" then over the years it dropped down to .015" to help with the over rich mixture right at launch until the motor cleared out and got to the correct AFR.

    I seriouly doubt that you or your motor and really tell the difference between a .015 or a .014-.016. I know that I probably can't set one that accurately. To some racers a tight .015 may be actually a .014 or a loose .015 may be a .016"
