Performance Distributors has applied their ignition expertise to the popular ZZ series of crate engines with their new ZZ Crate Engine D.U.I. Distributor. This new D.U.I. (Davis Unified Ignition) is specifically designed for the ZZ-4, ZZ-454 and ZZ-502 crate engines.
Two features distinguish the Crate Engine D.U.I. from the regular line of DUI Distributors. First, Performance Distributors calibrates the advance curve on a distributor machine to accommodate the GM Performance Catalog’s timing recommendations. The optimized curve provides instant throttle response and maximum performance throughout your rpm range, while protecting your crate engine from detonation. Pinpoint accuracy will be achieved by coordinating your mechanical advance with the proper vacuum advance. Secondly, a melonized distributor gear is used to mesh properly with the crate engine’s steel hydraulic roller camshaft.
The distributor comes complete, including the dependable Street/Strip D.U.I. Coil and Dyna-Module, which allow you to open up your plug gaps to .050”-.055”, burning your fuel more completely. Magnetic pick-up coil power is insured by aligning the teeth on the pick-up to the teeth on the shaft reluctor to very exact tolerances. An additional step that also insures maximum magnetic pick-up coil power is the hand setting of the endplay between the distributor gear and the distributor housing. Proper lubrication of the D.U.I. distributor, along with test firing of the electronic components, provides you with not only an excellent performing ignition system, but also with a very reliable one.
The ZZ crate engine DUI is hand built to exact tolerances. Each unit is polished and lubed so that all mechanical parts perform super smooth. Every distributor is test fired to insure all parts are working properly before leaving the facility. If you are looking for a high performance ignition with the simplicity of a one-wire hookup, then install the Performance Distributors ZZ crate engine DUI and start Driving Under the Influence of more horsepower and more torque!
The Performance Distributors ZZ Crate Engine DUI has a list price of $299.00 and is covered by a one-year warranty.
