NOT MANY PEOPLE know about this one! We’ve run it for years. The MSD Pro Mag has the wiring to use two pickups, one is in the Mag and picks up its firing point off of the main Mag Gear Shaft. The other can come from a Crank Trigger, we use both. We set the Crank Trigger at a higher timing degree & the Mag we set at a lower degree. Lets say 28 Degrees on the Crank Trigger and 24 Degrees on the Mag Generator. When The Track Slicks Up Flip The Trigger Switch From Crank To The Generator And Kill About 60 Horsepower On The Bottom, Making The Car Much Easier To Hook Up!
