The HT Monaro was introduced in 1969, as the facelift replacement to the highly successful HK. Missing from the HT lineup was the 327 cui engine, now replaced by a larger 350 cui. The larger engine pushed the output to 300 b.h.p. but only when paired with the 4-speed manual transmission. Upgrades from the HK also included the instrument cluster, with the tachometer now housed within the dashboard, the suspension was revised, and thicker brake discs.
Cosmetically the front grille was changed from metal to plastic, and the rear lights were now taller and wrapped around the car. The rear of the boot lid was also now a flat panel instead of having an undercut. The most notable upgrade was to the bonnet with the addition of twin air scoops, although they were more style than function.
The HT Monaro continued the racing success of the HK. In 1969 the Holden Dealer Team was formed and entered three HT Monaros in the 1969 Bathurst, with the HDT 44D car winning driven by Colin Bond and Tony Roberts. Norm Beechey also had success with the HT Monaro, winning the 1970 Australian Touring Car Championship.
