Some great pictures of Les 4 Heures du Circuit Le Circuit Mont-Tremblant, held on May 21, 1967 can be seen here: http://www.autocourse.ca/photos/saison1967/transam/transam/transam.html
The photos are courtesy of Yves St-Jean and the CASC Archives.
Several Camaros participated in this event and I have attached a few of the best pictures of them.
The first photo shows the start of the race. You can see the flag man about to waive the green flag for the standing start. The light blue #56 Camaro is the winning car of Dick Guldstrand/Tom Payne. It completed 118 laps.
The second photo shows the #24 Camaro of Don Yenko and Jerry Thompson. The car did not finish due to a suspension problem on lap 103. You can also see the white Yenko Stinger Corvair just behind the Camaro in this picture. It was driven by Donna Mae Mimms but failed to finish due to ignition and clutch failure on lap 18.
The third photo shows the #1 Camaro of Joie Chitwood. Did Chitwood drive this car or was it Corwin/Lynd, the only other Camaro drivers mentioned in the article race recap to finish the race?
The fourth photo shows the #777 Camaro of Craig Fisher. This car did not finish due to an engine failure on lap 51.
