Anyone know what car this is?

Good Day All,
The wife has been going through trunks of pictures(literally) to post halloween photos of decades past. These picks came out of one of the trunks, and as I didn't know her at the time I cannot identify the cars... By the cars, clothes, and track I know it's Riverside about 2-3 years before I started racing there('77). I have no idea who the people or driver Mark Saroyan is, but if I can find out what cars are being raced, I may be able to find out who this roll of film belongs to. Anyone recognize the cars/class? .......Thanks for your time, joeschmoe

Formula Ford is the class. I'd guess the single car is a Crossle 35F.

Thanks JacnGille!! I was thinking they might be, but I thought they were a little large....Thanks again!
