|From Drawing Board to Production
The Australian car passes over the same Belgium Block
Pavement on its way to one of the many special hills
at the proving ground. This is a 27 percent grade, a
car climbs 27 feet for every 100 feet of forward travel.
The Australian car takes to the high speed lane for an
engine performance test. It is powered by a six cylinder
valve and head engine with a displacement of 132 and
one half cubic inches. It has a bore of 3 inches, with
a 3 and 1/8th inch stroke.
The engine has an SAE rating
of 21 and 6/10ths horse-power, producing 54 brake horse-power
at 4000 revolutions per minute.
From designing boards,
from thorough research and from rigorous and exacting
tests made at proving grounds, General Motors Engineering
through commercial specifications supplied by the staff
of General Motors Holden have produced this new automobile
