Petty started second alongside long-time rival Bobby Allison. The majority of the 153 laps on the southern California road course were led between the two drivers - 75 by Allison and 60 by Petty. Interestingly, two drivers and teams who historically raced well at Riverside - Cale Yarborough with Junior Johnson's Chevy team and David Pearson with the Wood Brothers Mercury team - did not enter the race. Economic times for race teams was tough in 1975 - low race purses, high operating costs, limited sponsorship dollars. Riverside wasn't the only race where some of the more well-established teams chose not to enter in 1975.
