As the crankshaft turns, the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be triggered by other bolts, debris, or even vibrations which will cause a loss of power or engine damage. The MSD Flying Magnet Crank Trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This \"flying magnet\" design produces accurate trigger signals and the non-magnetic pick-up cannot be falsely trigge\u003c\/p\u003e\u003cp\u003eMSD crank trigger ignition kit, part number 8644, supplied new.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePowerful magnets are embedded in a billet aluminum trigger wheel.\u003c\/li\u003e\n\u003cli\u003eFits 429\/460 Big Block Ford.\u003c\/li\u003e\n\u003cli\u003eThe non-magnetic pickup cannot be false triggered.\u003c\/li\u003e\n\u003cli\u003eDoes not fit Cleveland blocks.\u003c\/li\u003e\n\u003cli\u003eAbsolutely the most accurate way to trigger the ignition.\u003c\/li\u003e\n\u003cli\u003eKits feature special brackets and mounting hardware for a variety of engines.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFits Big Block Ford V8 (429-460)\u003c\/li\u003e\u003c\/ul\u003e\u003cp class=\"pst-note\"\u003e\u003cem\u003eThis part is built for the engine families named above rather than for one body style.
