Jason Gomersall put his Holden Dealer Team inspired A9X Torana on top of the times in Touring Car Masters practice at Winton Raceway.
The Matt Stone Racing built Torana ran faultlessly on its competitive debut posting a new practice lap record to top second practice.
After posting the third fastest time in the opening session, Gomersall produced a 1:28.5800s to set the pace in the final 20 minute hit out.
The A9X Torana is the first to compete in Touring Car Masters as regulations now allow cars constructed up to 1978 to enter.
The Porsche 911 RS of Sven Burchartz ended the day second overall with his Practice 1 topping time just 0.12s shy of Gomersall.
John Bowe was third fastest behind the wheel of his 1974 Holden Torana, while Glen Seton and Jim Richards were fourth and fifth, within 0.7s of Gomersall's time.
The Touring Car Masters returns on Saturday for a 20 minute qualifying session before a 12 lap race scheduled to start at 1440 local time.
