As your source suggests, it seems that Chuck Kirkbride drove a Lotus 18 to victory, at the American Road Race of Champions, held in Daytona Beach, November 1967. [Although I believe that there are also mentions of a Lotus 23.]

SCCA (Sports Car Club of America) records confirm that four racers were on the grid for the Formula A race, and that Kirkbride was the only one to complete the race -- http://www.virhistory.com/cars/arrc/1967-res.htm

I am in contact with his daughter, who has his Heuer Camaro, his trophy and lots of photos, and I am optimistic that we will be able to tell the "back story" of these watches.

: In 1967 Chuck Kirkbride's car was a Lotus 18, a 1960 car.
: Here's a report:

: With the 3-litre F1 not yet in force, Formula A attracted
: hardly any worthwhile entries in its first few seasons. The SCCA
: national championship for FA was not even competed in 1965 so
: the first national champion in Formula A was Harry McIntosh in
: 1966 who beat a paltry field in his ex-F1 1.5-litre Brabham BT7
: (F1-1-63). The following year Chuck Kirkbride won in a Lotus 18
: (372) but he was the only finisher in his class and some three
: laps behind the best Formula B car. A lucrative professional
: series started in 1967 but was dominated by FB cars.

: It seems it was fitted with a Coventry-Climax FPF engine,
: which could have been any size from 1500cc to 2700cc. Here is a
: photo of it with the engine size given as 2497cc, which makes it
: a Formula One car from the 2.5 litre days. Wheels and tyres are
: 1960 F1 too in this picture. Don't they look skinny? There are
: also 3 Coopers, and I cannot see enough of number 30 to identify
: it.
