plugs and gap

Eddie wants to know what spark plug and gap you all are using with your MSD, not how to time travel to Pluto to figure out the range of pressure a collapsed O-ring will take before the ovalommeter explodes at 140,000 volts and cause the imploding of the navigators cranium over the course of 700 lights years at 2,578 miles per hour holy crap

So, I guess you don't know either?

If I ever get mine back together (before I die) I might do some testing. Buy a performance meter. Make some test runs. Hire a dyno.

Otherwise, gap 'em anywhere from 35 to 60 and forget 'em.
