As far as I can tell, there are only 2 pictures without names.
The first group race picture is from a track in the middle of a park called La Mirada Park. The park is only about 5 miles from where I live now, but there is no longer a track there. The racers in that shot are; #43 is Stu, #101 is a lower level racer named Jerry Railsback, #20 is Harry Leary, and #3 is Perry Kramer.
A couple of pictures below that, the caption only hints at who it is. It is a famous racer turned artist/cartoonist, who made custom number plates and then went on to even bigger and better things. #1311 is Bob Haro.
All the other pictures have names in the captions that tell who they are.
There you go.
