First photo looks like Jim McElreath after winning Little 500 for Dizz Wilson in 1961. The story goes that after the win he and Johnny Rutherford traveled to Indianapolis to see the 500 for the first time in person. Knowing no one they slept outside in Leonard Park in Speedway, Indiana and actually had to both get under a picnic table when a rain shower popped up during the night. A year later he was the Rookie of the Year in the 500. I'm not sure about the second photo. Could that be Bobby Unser in the #4 midget? Thanks Rootie!
