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.
