Davis Unified Ignition (D.U.I.) Ford Hot Forged Distributors are just the replacement needed for Ford engines demanding toughness and durability. Hot forging provides a denser, stronger and more durable distributor compared to cast aluminum and billet distributors. Machined using computerized CNC mills and lathes to create exact tolerances. Each unit is tested for thermal shock and RPM accuracy between 8,000 and 10,000 rpm’s. Included is a high dwell Dyna-Module which increases spark duration for better throttle response and more low end power. Provide your EFI Ford with reliable performance and show quality looks!
