I have some old paperwork from my old man's car owners. In the late 60's, he ran super modifieds in Michigan. One of those items was a pay sheet of what the car won every night. The one that stuck out the most, was a show on July 5 in 1968, it paid $1000 to win. My father took 3rd in the heat race, and 6th in the feature, and he won a total of $17. $2.00 for the heat, and $15.00 for the feature. That is what I remember, usually big money to win, but peanuts for everyone else. May not have been that way for the national touring stuff, but it was that way for the local "big shows".
