Stop chasing scatter.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA Flying Magnet crank trigger kit for small block Ford Windsor engines — 289, 302, and 351W — using four magnets embedded in a 6.562-inch billet aluminum wheel to deliver a 4X trigger signal straight off the crankshaft. Brackets and hardware included.\u003c\/p\u003e\u003cp\u003eRacers figured this out a long time ago: one of the best things you can do for an engine is stabilize the ignition timing. Reading it at the crankshaft instead of through the distributor drive removes the slop in between. MSD calls the Flying Magnet system absolutely the most accurate way to trigger the ignition.\u003c\/p\u003e\u003cp\u003eThe design is what makes it dependable. Four powerful magnets are embedded in a billet aluminum trigger wheel, 6.562 inches in diameter and 3\/8 inch wide, passing a stationary non-magnetic pickup. MSD states that pickup cannot be false triggered. The sensor measures 3\/4 by 2.25 inches, compact enough for a crowded front of engine.\u003c\/p\u003e\u003cp\u003eThe kit includes special brackets and mounting hardware, so bracket work is not left to you. Designed for MSD 6, 7, and 8 Series ignitions, in black. Be clear on one thing before ordering: MSD lists this kit as Emission Code 4, racing use only.\u003c\/p\u003e\u003ch3\u003eWhat's In the Kit\u003c\/h3\u003e\u003cp\u003eEverything MSD confirms in the box:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ex1 Billet Aluminum Trigger Wheel — 6.562\" Diameter, 3\/8\" Wide, Four Embedded Magnets, Black\u003c\/li\u003e\n\u003cli\u003ex1 Non-Magnetic Pickup — 3\/4\" x 2.25\", 4X Trigger\u003c\/li\u003e\n\u003cli\u003eBrackets and Mounting Hardware\u003c\/li\u003e\n\u003cli\u003eA piece-by-piece contents list is not published\u003c\/li\u003e\n\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003eFits: Small Block Ford Windsor — 289, 302, 351W.\u003c\/li\u003e\n\u003cli\u003eRequires: an MSD 6, 7, or 8 Series ignition.\u003c\/li\u003e\n\u003cli\u003eTrigger Wheel: 6.562\" Diameter, 3\/8\" Wide.
