Unlike his four previous titles, though, Geoghegan’s
last ATCC victory came in the first year Australia’s
premier touring car title expanded to a multi-round
series with races held in most states. This included
the nail-biting finale at Symmons Plains in Tasmania,
when he beat Alan Hamilton’s Porsche 911TR to the
crown by a single point.
Geoghegan continued to race his much-loved
Mustang in the 1970 and 1971 ATCC battles, when
it sprouted large wheel-arch flares to house the
fatter 10-inch wide tyres permitted for the Improved
Production cars by that stage.
Even so, the ageing Mustang faced increasingly
tough competition from potent new muscle cars like
Beechey’s HT Monaro GTS 350, which in 1970 became
the first Holden and first Australian car to win the
ATCC. And Bob Jane’s exotic 7-litre big block Camaro
ZL-1, which won the 1971 and 1972 titles.
Arguably Geoghegan’s greatest competition, though,
came from another Mustang driven by Allan Moffat,
which is widely regarded as the most famous and desir-
able Australian race car of all.
Moffat’s 1969 Boss 302 Trans-Am, resplendent in
the bright red paint of his sponsor Coca-Cola, was one
of only a handful built by Ford’s factory teams to tackle
rival Chevrolet in the 1969 US Trans-Am series.
Hand-built by Bud Moore Engineering, the 1969
Boss 302 Mustang Fastback used only the best compe-
tition components. It featured the latest Boss 302 race
engine, superbly designed roll cage and suspension and
even subtle body re-profiling for better air penetration
at high speeds. It was the closest thing you could get to
a purpose-built race car in a production car body shell.
Although Moffat never won the ATCC title after four
years of trying, the mighty Boss finished its six-season
career in Moffat’s hands with a staggering 101 race
wins from 151 starts. It also set lap records at every
circuit Moffat raced on and was involved in many
thrilling battles with Geoghegan’s 1967 Mustang from
1969 to 1972.
A change in the touring car rules for 1973 saw the
creation of a new class called ‘Production Touring
Group C’, which in effect combined the old Series
Production and Improved Production classes into one
new category. As these cars were to compete for the
ATCC and Manufacturers Championship, Moffat’s
Mustang was consigned to the Sports Sedan ranks.
The first Mustang ATCC era was over.

Ford fans expecting a repeat of the Mustang’s 1960s
dominance when the pony car returned in the 1980s
were to be disappointed.
The switch from home-grown Group C to the FIA’s
international Group A rules in 1985 may have opened
the doors to more makes and models from overseas,
but it did nothing to help Australian cars.
Overnight Holden’s VK Commodore became an
underpowered and overweight slug as its 308ci
(5044cc) V8 placed it in the over-5000cc engine group,
which meant it was burdened with about 180kg of
ballast to bring it up to a hefty 1400kg minimum
weight. The tight new engine restrictions also knocked
the power output back to around 300hp.
Holden performed a partial fix for 1985 by slightly
de-stroking its V8 from 5044cc to 4987cc, which
dropped the Commodore into the under-5000cc divi-
sion to get a crucial 75kg drop in minimum weight
(1400kg to 1325kg).
By comparison, Ford Australia found itself in a
similar situation to the mid-1960s as it had nothing in
its Falcon line-up that could be remotely competitive.
So reigning champion Dick Johnson and other Ford
loyalists were realistically left with the choice of two
imports – the UK’s 2.8-litre V6-powered Sierra XR4i or
the 4.9-litre (302ci) V8 Mustang from the USA.
On paper the Mustang was the more practical choice
given that Eric Zakowski’s Zakspeed team in Germany
had already homologated and built Mustang GTs
for European Group A touring car racing in 1983.
And Australian teams were more familiar with the
Mustang’s venerable small-block Windsor V8 and
muscle-car mechanicals. Johnson purchased two of
the Zakspeed-built Mustangs in 1984 with a view to
finishing what Zakowski’s team had started by making
the compact V8 American coupe into a race winner.
