{"product_id":"hly-556-170","title":"8-Inch 12-1X Crank Trigger Kit, BBC, Hall Effect","description":"\u003cp\u003eUpgrading to an MSD Flying Magnet Crank Trigger Kit will deliver the precise and reliable signal that a high performance engine requires. This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system \/ ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI\/RFI interference\/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high quality timing pointer and the use of a direct bolt-on, degreed balancer (see below list for recommendations), you'll be able to adjust timing in the precise increments required for your engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e\u003cbr\u003eIncluded installation instructions cover mechanical setup and provide step-by-step Holley EFI Software Setup\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e For Big Block Chevrolet\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIn the box:\u003c\/strong\u003e Pickup\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBracket Color\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBracket Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSilver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDiameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8-inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBig Block Chevrolet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensor Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHall Effect\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTrigger Wheel Color\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSilver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTrigger Wheel Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBillet Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTrigger Wheel Outside Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTrigger Wheel Thickness\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3\/8 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eProduct Video\u003c\/h3\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:1em 0;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/6G3R9GdXV4w\" title=\"Product video\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen style=\"position:absolute;top:0;left:0;width:100%;height:100%;\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:1em 0;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/cFj0A106QG8\" title=\"Product video\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen style=\"position:absolute;top:0;left:0;width:100%;height:100%;\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":44472159567937,"sku":"556-170","price":760.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.theefistore.com\/products\/hly-556-170","provider":"The EFI Store","version":"1.0","type":"link"}
