{"product_id":"comes-with-an-iron-gear-and-with-not-work-with-factory-roller-cams-2","title":"Proform 66980BK Comes With An Iron Gear and With Not Work With Factory Roller Cams","description":"Utilizing the durable and dependable High Energy Ignition (HEI) system pioneered by GM, these distributors avoid the unsightly wiring of stock Ford electronic ignition systems by installing this one-piece distributor with an internally positioned coil and module. Easy to install: just connect one 12-volt hot wire to the distributor (has optional tach hook-up). These units offer calibrated advance curves that are optimized for maximum combustion efficiency and for the elimination of detonation damage and throttle ping. Assembled from precision-madeparts for advance curve smoothness. Offers longer term durability and a higher voltage spark that permits a bigger spark plug gap, resulting in more power and reduced plug fouling. Each unit includes a high-power coil, a premium hi-dielectric cap with brass terminals, and a low-saturation ignition module. By eliminating the stock-Ford ballast resistor, more ignition voltage results in improved spark. Incorporates easily found High Energy Ignition (HEI) replacement parts. Assembled with upper and lower bushings (stock Ford distributors have only a single bushing). Technical Note: Gear not compatible with roller cams. If using roller cams, please contact the cam manufacturer for proper gear selection.","brand":"Proform","offers":[{"title":"Default Title","offer_id":51211318034747,"sku":"BCHW_66980BK","price":325.67,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/5958\/2011\/files\/fc82fa87dc612.jpg?v=1777701586","url":"https:\/\/performancepartscanada.ca\/products\/comes-with-an-iron-gear-and-with-not-work-with-factory-roller-cams-2","provider":"Performance Parts Canada","version":"1.0","type":"link"}
