The 1973 Bathurst race would test the 17 Toranas facing the starter.
The new distance of 1000km placed extra stree on the cars, and regulations now put cars like the Torana in the same class as Falcons and Chargers. Most of the private team Toranas couldn't keep up with the Falcon's pace and mechanical failure thinned the field by the mid-race.
But the Holden Dealer Team Toranas used a taller 2.78 to 1 final drive. They could challenge the Falcon of Allan Moffat and did so aggressively. But a put stop drama meant Peter Brock, sharing with Doug Chivas, placed 2nd. Colin Bond with Leo Geoghegan as his co-driver drove a faultless race crossing the line in 3rd place. Full credit to HDT!
