Advantages of MSD 6AL over FMS Ignition Box
I have a 351W crate motor with the FMS Ignition Control box and duraspark distributor. The ignition box number is M-12199-c301. It has the blue wire strain relief and has a tach output terminal and RPM limiting socket. It is labled states "made by MSD".
What would be the advantage of switching to the MSD 6AL box?
