Proform 66980B Vacuum Advance HEI Distributor with Steel Gear and Blue Cap for Ford 351C-400/429/460

High Performance HEI Distributor & CoilBig Block Ford 429/460, 351C, & 351/400M Blue Cap 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 billet roller cams.Emissions Note:This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.CLICK THIS LINK FOR IMPORTANT CARB & EPA EMISSIONS INFORMATION ABOUT THIS PART
