The Holden Grey motor is often referred to as the Holden side plate. The engine earned its name as they were painted grey from the factory. They came in 2 sizes, 138ci and 132ci. More engineering and after market modifications have gone into this engine than any other engine in Australian automotive history.

Norman supercharger for Holden Grey Motor

The Norman supercharger is probably the most well know supercharger for the Holden Grey motor.  These days there isn’t alot of them or information around but they still pop up from time to time.  There were a few variations including water and air cooled variants. 

In a recent Street machine article there was a FJ that many years ago fitted with a Norman charger ran a 12 second quarter mile.  That's quite impressive for a 2.3 litre motor build in the late 50's

Here are some pictures:
