A 1967 Camaro RS convertible was used in some type of official capacity at the Monterey Grand Prix held at Laguna Seca Raceway in Monterey, California on October 16, 1966. This was the fourth event of the inaugural season for the SCCA Canadian-American Challenge Cup (Can-Am.) In addition to Rally Sport equipment, the picture shows the car also had rally wheels, white wall tires and bumper guards. This event was held a little more than two weeks after the Camaro was officially introduced to the public on September 29, 1966. It was won by Phil Hill in a Chevy powered Chaparral 2E.
Parnelli Jones can be seen in the white Firestone race suit on the drivers side of the Camaro. He won the 2nd of two 53 lap heats. Phil Hill won the first heat and came in 2nd place in the second and was declared the overall winner of the event.
A sticker/decal on the door of the Camaro says "SCRAMP OFFICIAL." SCRAMP stands for the Sports Car Racing Association of the Monterey Peninsula which put on the event. Notice the car has Manufacturer license plates.
