A Chevrolet Monza Sports Sedan originally built and campaigned by Graeme Whincup is set to make its race return this weekend at Mallala in South Australia.

The car was the second Monza constructed by Whincup, the uncle of seven-time Supercars champion Jamie, making its debut in 1985.

It was driven by Whincup until nearly the turn of the millennium and later spent time at Dreamworld on the Gold Coast, dressed as a replica of the Bob Jane Monza raced by Peter Brock.

Historic racer and car collector Carey McMahon then purchased it and spearheaded a full restoration, including a return to its Whincup colours.

McMahon today revealed images of the finished product on social media, complete with replica decals supplied by Whincup himself!

According to McMahon the car’s fresh engine produces 623bhp which, in a 1000kg, aluminium-monocoque chassis makes for a formidable weapon.

“The Fataz engine from Ian Woodward has insane horsepower and torque so it should be a real handful!” he wrote.

The Monza will be one of a number of historic Sports Sedans in action this weekend at the All Historic Mallala meeting.
