Our Street/Strip Chevrolet DUI Distributor is now available for the popular
ZZ series crate engines! This new DUI (Davis Unified Ignition) is designed
for the ZZ-4, ZZ-454 and ZZ-502. A special timing curve and a melonized
gear sets this distributor apart from our standard DUI. The advance weights
and springs are tuned specifically for these crate engines. The optimized
curve provides instant throttle response and maximum performance all
through the RPM range without any pre-detonation. The melonized gear is
installed for proper meshing with the roller cam. Our 7000 RPM Street/Strip
Coil and high dwell Dyna-Module are included for the hottest spark output
available. No add-on spark box is necessary as our coil and module will fire
a massive .055" plug gap! The large gap provides a more complete burn of
the fuel mixture for increased horsepower and torque. Vacuum advance is
installed for improved fuel economy and cleaner spark plugs. 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 our facility.
If you are looking for a high performance ignition with the simplicity of a one
wire hookup, then install our ZZ crate engine DUI and start Driving Under
the Influence of more horsepower and more torque!

The ZZ Crate Engine DUI is covered by a one year warranty from date of purchase.

LIVEWIRES

Delivering a high voltage spark to the plug requires a quality spark plug wire.
Our LiveWires are unsurpassed in quality by offering low resistance and high
temperature protection. The 8 mm wire is covered by a heat treated fiberglass
sleeve that protects the wire up to 1400° F. The spiral wound core is radio
suppression so there is no radio noise or computer interference. Unlike universal
plug wire sets, LiveWires do not require any assembly. All sets are custom fit and
numbered at each end for the correct cylinder. Colors available are black, blue,
red, purple and yellow.
Recommended Part Numbers:
C9051 - (Under The Headers) $99.00
C9053 - (Over The Valve Covers) $99.00

DYNA-MODULE w/ BUILT-IN REV LIMITER

Our high dwell Dyna-Module is now available with a built-in adjustable Rev Limiter! This
module performs the same as our regular Dyna-Mod by increasing spark duration but
offers the added convenience of protecting your engine from over revving. The rev limit
is adjustable through a small rotary dial on the end of the module from 5000 to 10,000 rpm.
The module also includes Traction Control Detection which immediately slows the vehicle
when a sudden change in ignition signals is detected. Works with all of our DUI and HEI
type distributors that utilize the 4 pin module.
Part# RL-000222 (Module w/ Rev Limiter) $125.00
Substitute the Rev Limiter Module for the standard 4 pin module on any DUI by adding $76.00 to the distributor
price and the letters RL in front of the part number.

 

 

 

DUI REV LIMITER

Protect your engine from over revving with the DUI Rev Limiter. The D.U.I. Rev Limiter
drops one cylinder at a time very smoothly. This prevents fuel from loading up on the
plugs. This also avoids backfires and engine damage. Set your RPM limit with plug-in
modules. A 6000, 7000 and 8000 RPM module is included with the rev limiter. Other
RPM increment modules are available separately if needed. This unit works great with
all of our DUI distributors.

BATTERY AND TACHOMETER CONNECTORS

These plastic insulators and brass terminals make your power supply connection
and tach connection to the DUI Distributor super easy! They plug directly into the
cap and coil assembly and the locking tabs prevent lost connections due to vibration.
The Battery and Tachometer Connectors are priced separately so one of each will
be needed for the hot wire and tach hookup.
