Deluxe Chevy D.U.I.
The Deluxe D.U.I. has 4 terrific features included in one Davis Unified Ignition package. First the new Cross-Fire Cap allows you to route your plug wires neatly on each cylinder bank. Makes plug wire routing easy. Second, is the
Adjustable Slip Collar. The unit features a slip collar with 7/8” of adjustability. Insures a precise installation. Third, a Carbon Ultra-Poly composite gear is used. It is compatible with any camshaftsolid, hydraulic, factory roller, or steel billet roller cam. Unmatched durability! Fourth, every D.U.I is calibrated on a distributor machine, providing a super smooth advance curve.
