What's in the Box


The 602/604 DUI is designed specifically for these crate engines with two features that set it apart from regular Racing DUIs. First, the mechanical advance is calibrated on a distributor machine with an aggressive and accurate timing curve designed to meet the requirements of these crate motors. This special racing curve will ensure maximum performance and get your car out of the corners faster. Second, a melonized
gear is installed on the distributor (instead of the stock cast gear) which is compatible with factory roller cams. 

  • Capable of turning 9000 RPM
  • No external spark boxes or coils are needed
  • Easy drop-in installation with a one wire hookup
  • Sends 2-3 times more spark into the combustion chamber than a magneto
  • Allows spark plug gaps to be opened up to .055"
  • Only pulls 2-3 amps (other systems draw 10+ amps)
  • Key distributor parts are polished and lubed for smooth operation

Available in "Stealth" version with no decals and a black cap for a bone stock appearance.
