Daytona 500 After falling back several laps due to overheating, Richard Petty pulled forward Benny Parsons in his draft to catch Pearson. With three to go Pearson moved into a group of lapped cars that included Cale Yarborough; inexplicably Yarborough got into Pearson and David spun down the backstretch. The win was Parsons' first since 1973.
Richmond 500 With a field of only 22 entries due to a dearth of team sponsorships, Petty led 444 laps and won by six laps. Cale Yarborough was among the teams not entered, due to losing Carling sponsorship after the 1974 season.
Carolina 500 In below-freezing temperatures, Cale Yarborough edged Pearson for the win while Petty finished nine laps down due to the same overheating problems that had plagued him at Daytona.
Atlanta 500 Petty and Pearson engaged in a running duel for the lead, but Pearson lost a lap in the final 100 miles. A late caution set up a one-lap duel between Petty and Buddy Baker; Petty contended the race ran past 328 laps but NASCAR showed scoring cards proving it had run the correct distance; among those who scored the race was Richard's daughter Sharon, who said Petty "went by 328 times."
Rebel 500Darlington Raceway once again proved tougher than Richard Petty as the #43 Dodge crashed out after 159 laps. Benny Parsons and David Pearson got into the late duel for the lead; when Pearson dove under Parsons entering Turn One on lap 350 both cars hammered the wall and ground to a halt. Bobby Allison, who'd been two laps down earlier, unlapped himself and edged Darrell Waltrip and Donnie Allison nose to tail at the stripe.
Winston 500 Tragedy blackened Buddy Baker's first win since 1973 and the first win for team owner Bud Moore since 1966. Richard Petty's wheel well caught fire while leading and he pitted; his brother in law Randy Owens fitted a hose to a pressurized water tank; the tank exploded, nearly landing on Petty's roof, and Owens was killed. Baker edged Pearson at the stripe while Dick Brooks and Darrell Waltrip had sparkling efforts in finishing out the top four. The race lead changed 51 times among 13 drivers.
Music City 420 The race was dominated by third-year driver Darrell Waltrip, his first Winston Cup Grand National win.
Michigan 400 In a highly competitive race that saw 44 lead changes, Pearson edged Petty for his second win of the season while Dave Marcis and Cale Yarborough finished third and fourth; the top four combined to lead 180 of 200 laps. Petty increased his point lead to 441 over Marcis.
Purolator 500 Controversy marred the finish. The lead changed 43 times despite a ninety-minute delay for rain near halfway. Pearson took the lead with 14 to go, but in the final seven laps the Wood Brothers Mercury smoked heavily, to where by Lap 198 it was lapping its own smoke. At that point NASCAR black-flagged Pearson, but the rules allowed a three lap period to obey the flag and there were only two laps to go. It was the third win of the season for Pearson.
Talladega 500 Multiple tragedies surrounded the seventh running of NASCAR's late-summer 500-miler at Talladega. Gene Lovell, crew chief for Grant Adcox, died of a heart attack; Adcox withdrew and first alternate Tiny Lund got his starting spot. Mark Donohue drove a Porsche IMSA racer to a new closed-course speed record of 221 MPH (breaking A.J. Foyt's 217 MPH record in his Indycar the year before) before pole qualifying; Donohue was killed ten days later during the Austrian Grand Prix. The 500 itself was scheduled for August 10 but was rained out until the 17th. Early in the race a six-car melee erupted and Lund was smashed through the driver side by another car; he succumbed to massive internal injuries. Dick Brooks then survived a furious tumble down the backstretch in the middle of the race. Buddy Baker held off Richard Petty at the stripe after 60 lead changes among 17 drivers.
Champion Spark Plug 400 A six-car crash pierced the backstretch guardrail and stopped the race for half an hour. A late caution set off a five-lap shootout as Petty and Pearson fought for the lead; the lead changed on every lap before Petty drafted past Pearson for the win.Cale Yarborough survived a spin after colliding with Dave Marcis and finished third; the two exchanged words after the race.
Southern 500Bobby Allison, despite breaking a suspension piece in the final 50 laps, completed a season sweep at Darlington as he outlasted Richard Petty, who competed despite illness and heat, needing relief help from Dave Marcis.
Delaware 500 Petty put the entire field two laps down, but with 150 to go a backmarker's blown engine sent debris under the STP Dodge and snapped a tie rod. Petty's crew needed eight laps to fix the problem and he restarted six laps behind Lennie Pond and Cale Yarborough. Pond fell out and Cale fell back; Petty kept lapping the field until he got back onto the lead lap; Buddy Arrington then came to a stop, necessitating a late yellow. Petty won handily and Dick Brooks finished second, upset because Arrington had purchased a transporter from Petty; said Brooks, "I guess Arrington needed that truck paid for."
Los Angeles Times 500Buddy Baker initially was not entered in NASCAR's season finale but Bud Moore had secured sponsorship from Norris Industries so Baker flew out to LA and led 148 laps, winning by 30 seconds over Pearson. Richard Petty led but fell out for the second straight year with engine failure; it was also his fourth DNF in his last seven races.
