Holden Grey BOSCH Hybrid HEI Electronic Distributor

This distributor is a development that along with modified internals marries the top half of a BOSCH electronic HEI distributor with the lower half of an original cast iron BOSCH Holden Grey Motor points type distributor.  Uses original BOSCH control module (which is usually mounted on the integral "balcony" on the side of the electronic distributor housing) but is now remote mounted for use with the hybrid distributor.  Remote mounting is primarily for packaging reasons, but also has the advantage of removing the module from close proximity to direct engine heat and vibration.  Companion low resistance coil is used and distributor provides variable/active dwell control and high energy spark.

Allows use of 0.060" plug gaps and provides a fully functional true electronic bolt-on HEI system for Grey Holden engines.  Not to be confused with simply fitting an "electronic points" module to a standard distributor which maintains an essentially fixed dwell and points type coil.

Ignition package is for customer in NSW running Holden Grey engined nostalgia drag car.

Modified Holden Grey Distributors

Two more cast iron BOSCH Holden Grey engine distributors off to customers in Western Australia this week.  Both re-curved to suit customers' supplied engine specifications.  Single point unit has typical 6 cylinder 38 degrees dwell and dual point has 48 degrees dwell.  Both retain these dwell readings to beyond 7000 crankshaft RPM under rig test.  Both units have vacuum advance deleted and fixed breaker plate assemblies.
