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.

AUSCA Sports, Built by Bacchus in Adelaide in 1959, one of Paul England's 16 FRP bodies which has a serious resemblance of the 1955 Maserati's A6GS. Powered by modified Holden grey motor, triple carburettors, 3 speed modified gearbox. 

CAMS Certificate of Description a truly historical master piece with Jack Brabham's signature under the bonnet along with other motor sport legends. Competively raced on many of the Australian tracks. 

The grey motor has been modified particularly with the head, larger valves, double valve springs, I do not know what has been done to the pistons and rods, but I know that changes have been made, as it loves revs, it just sings at 5,000. The crank shaft appears to be original. The sump has been modified using baffles to keep the oil back at the pump when severe braking and G forces on the race track. the cooling system has a total change using a header tank, you may get the drift from the pictures. Triple SUs, with a much non standard exhaust. Electronic ignition.
The gear box remains much the same ad the usual grey, heavier clutch, larger main drive shaft and bearing and have modified, larger,  the cir-clip at the end as it was giving problems popping off changing down at high revs. Running second third , third to second in a straight line is good for the race tracks I use.
