Although this decision was later reverted to no suspension at the drivers' meeting, Harvey decided to opt-out of Speedway to go road racing.
In 1976, Harvey won the first round of the Australian Touring Car Championship in a one-off drive in a B&D Autos-sponsored Torana L34 at Symmons Plains.
Later in the year Harvey was signed up to co-drive with Colin Bond in the Holden Dealer Team Torana L34 which finished a close second in the Bathurst 1000.
The Holden hierarchy decided it would be good 'politic' to let Bob Morris and British sportscar racer John Fitzpatrick keep the win.
The Harvey car effectively became Brock's backup, notably winning the 1978 Rothmans 500 event at Oran Park teamed with Charlie O'Brien.
The race win was controversial at the time as many felt Brock and Perkins should not have been allowed to move into the HDT's second car after theirs retired.
Harvey won the 1986 Pukekohe 500 with Neal Lowe in their new Group A SS VK Commodore, and the pair finished second to HDT teammates Brock and Allan Moffat at the 1987 Nissan 500 Wellington.
Harvey told his side of the story of the split in Bill Tuckey's 1987 book The Rise and Fall of Peter Brock.
Later at the Spa, 24 Hours in August, Moffat, and Harvey achieved a class win and finished 4th outright behind the works BMW Team M3's.
After Moffat abandoned the Commodore in favor of Andy Rouse's Ford Sierra RS500, Harvey missed the 1987 James Hardie 1000 which was a round of the WTCC.
He was recommended for his professionalism and discipline by Ray Borrett (Holden's reliability and “skunkworks” motor sport engineer).
Harvey's last Bathurst 1000 was in 1988 where he teamed with Kevin Bartlett in a Holden VL Commodore SS Group A SV to finish in 14th after qualifying 22nd.
