Official
That's what I thought, as though someone put the '69 Pacer decals on a '67.
Doesn't look that long of a word or it would all be scrunched together. Looks like USAC or such.
Scott, what race series initials could it be?
I've been trying to figure it out as well. Every time I look at the original picture, non expanded version, I tend to think that it does say "OFFICIAL"
Going on the theory that the dealership provided the Camaro to a local track and then sold it as a used car once the racing season was over, I tried to figure out the race tracks that would have been in Ontario during the time period. The Wiki list of Canadian race tracks shows many contenders:
https://en.wikipedia.org/wiki/List_of_auto_racing_tracks_in_CanadaPaved Ovals:
Barrie Speedway operated between 1965 - 2014 (Barrie, Ontario)
Capital Speedway operated between 1961 - 2014 (Ottawa, Ontario)
Checker Flag Speedway operated between 1961 - 1992 (Windsor, Ontario)
Delaware Speedway opened in 1952 (Delaware, Ontario)
Flamboro Speedway opened in 1961 (Hamilton, Ontario)
Jukasa Motor Speedway (originally called Cayuga Motor Speedway) operated between 1966 - 2010 (Cayuga, Ontario)
Peterborough Speedway opened in 1967 (Peterborough, Ontario)
Pinecrest Speedway operated between 1948 - 1976 (Concord, Ontario)
Road Courses:
Harewood Acres operated between 1956 - 1970 (Nanticoke, Ontario)
Mosport Park (now known as Canadian Tire Motorsport Park) opened in 1960 (Bowmanville, Ontario)
Most of these racetracks are hundreds of Kilometers away from Chatham, Ontario where the dealership was located. The closest ones were Checker Flag Speedway in Windsor and Delaware Speedway in Delaware. They are both around 80 Kilometers away.
Now the Mosport Park road course did have a USAC sanctioned race of Indycars or to be period correct, USAC Champ Cars, held on July 1, 1967 but I have yet to find a definitive picture showing what was used as the pace car.
My best guess is that this Camaro was used as a pace car at some local track and put up for sale as a used car when the race season was over or it was traded in on a new car by someone who acquired it from the racetrack.
