The GM 602 and 604 crate motors have become popular spec engines for a number of sanctioning bodies in circle track racing. Classes requiring these factory sealed engines are designed to keep competition equal. To enhance the performance of your GM crate engine and outperform the competition, install our new 602/604 Racing DUI Distributor!The 602/604 DUI is designed specifically for these crate engines with two features that set it apart from our regular Racing DUI. First, we calibrate the mechanical advance 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, we install a melonized gear on the distributor instead of the stock cast gear. The melonized gear is required for the steel hydraulic roller camshafts that come in the 602 and 604 engines. Along with these features, the DUI comes complete with our Racing Coil and Dyna-Module. These race proven parts produce the ultimate spark output by allowing plug gaps to be opened up to . 055". The larger plug gap will provide a more complete burn of the fuel mixture by exposing more spark in the combustion chamber. No add-on spark box is necessary!

Each 602/604 DUI is hand built to exact tolerances. We align the pick-up coil to the shaft reluctor and set the end play between the gear and the housing for accurate and precise trigger signals. Key parts of the distributor are polished and lubed for super smooth operation. The DUI is test fired before leaving our facility to insure all components are working properly. For a high performance ignition system with unsurpassed reliability, the 602/604 Racing DUI is the best distributor available for your crate engine. Available in "Stealth" version with no decals and a black cap for a bone stock appearance.
