In the mid-1960s, NASCAR faced one of its biggest challenges. A powerful engine changed the game, but it also caused serious conflict behind the scenes. Richard Petty, a rising star, found himself at the center of a fight that went beyond the race track. This battle led to an unexpected decision that shook the sport. The effects of this moment still echo today, shaping the path of NASCAR and its drivers in ways few could imagine.
The 426 Hemi Dominance and NASCAR’s Response
The 1964 NASCAR season is remembered as one of the most dominant performances by a manufacturer and driver combination in racing history. Chrysler’s introduction of the 426 Hemi engine, a revolutionary powerplant, transformed the competition. Richard Petty, driving a Plymouth Belvedere powered by the new Hemi, went on a tear, winning 26 races for Plymouth—nine of them by Petty himself—and securing the Grand National championship. The Hemi’s superior design and power left rival manufacturers Ford and General Motors struggling to keep pace.
As the season progressed, the disparity between Chrysler and its competitors became increasingly apparent. Ford and GM, frustrated by their inability to match the Hemi’s performance, pressured NASCAR to take action. NASCAR President Bill France Sr. faced a dilemma: maintain the status quo and risk losing Ford and GM, or ban the Hemi and risk alienating Chrysler. In November 1964, France opted for the latter, announcing stricter rules that effectively banned the 426 Hemi for the 1965 season. The justification cited was a requirement that engines must be available in production vehicles, which the Hemi was not at the time.
The Boycott: Petty and Chrysler Take a Stand
The decision to ban the Hemi was met with outrage by Chrysler and the Petty family. Chrysler’s management and the Petty Enterprises team saw the move as unfair and targeted specifically at their success. Rather than switch to a less competitive engine or car, Chrysler and its top factory teams—including Richard Petty, David Pearson, Paul Goldsmith, Bobby Isaac, Jim Paschal, and LeeRoy Yarbrough—chose to boycott NASCAR for the 1965 season.
For Richard Petty, the reigning champion, the boycott was a difficult but necessary decision. He remained loyal to Chrysler, turning down offers from Ford-backed teams to switch allegiances. The boycott left NASCAR without some of its biggest stars and most popular cars, significantly altering the competitive landscape for the year. Fans of Mopar (Chrysler’s performance division) were left disappointed, and the absence of the Petty blue No. 43 was deeply felt at tracks across the country.
Drag Racing: Petty’s Alternative Path
With NASCAR competition off the table, Richard Petty and his team turned their attention to drag racing. Petty Enterprises built a special Plymouth Barracuda, powered by the outlawed 426 Hemi engine, and emblazoned the car with the word “OUTLAWED” on the door—a bold statement of defiance. The car was first equipped with carburetors, then later with Hilborn fuel injection, and featured an altered wheelbase for better weight distribution in drag racing.
Petty’s foray into drag racing was not without its challenges. In February 1965, during a test session at Southeastern Dragway in Dallas, Georgia, tragedy struck when the Barracuda crashed, killing an eight-year-old boy and injuring seven others. The accident was a devastating moment for Petty and his family, and they faced lawsuits totaling over $1 million. Settlements were reached within a month, but the emotional toll lingered. Despite the setback, Petty persevered, building a second Barracuda and continuing to compete in drag racing throughout 1965 and into early 1966.
Petty’s drag racing campaign was marked by both adversity and success. The second Barracuda, known as the “43 JR,” was highly competitive, winning its class at the Bristol Spring Nationals and participating in numerous match races against prominent drag racers. Petty’s willingness to adapt and his resilience in the face of adversity demonstrated his versatility and determination as a racer.
The Return: Compromise and Comeback
As the 1965 season progressed, NASCAR began to feel the effects of the Chrysler boycott. The absence of Chrysler’s top drivers and cars led to a less competitive and less exciting series, with Ford teams dominating the field. Attendance and fan interest suffered, and NASCAR’s leadership recognized the need for a compromise.
In June 1965, NASCAR and the United States Auto Club (USAC) agreed on a unified set of rules that allowed the Hemi engine to return under certain conditions. The revised guidelines set a minimum weight for cars and permitted the Hemi in the 1965 Plymouth Fury and Dodge 880 and Polara on tracks over one mile in length. On shorter tracks, the Hemi was allowed in the Plymouth Belvedere and Dodge Coronet.
With the rules change, Richard Petty and Chrysler returned to NASCAR competition. Petty climbed out of his drag racer and back into a Plymouth Fury, quickly reasserting himself as a contender. In just 14 starts that season, he won four races—accounting for all of Plymouth’s victories in 1965. The return of Petty and Chrysler restored balance to the series and reignited fan enthusiasm.
The episode had a lasting impact on NASCAR and the sport’s relationship with manufacturers. The 1965 boycott highlighted the delicate balance between innovation, competition, and regulation in motorsports. For Richard Petty and the Petty family, the experience demonstrated their loyalty to Chrysler and their ability to adapt in the face of adversity. The legacy of the 426 Hemi and the 1965 boycott remains a defining chapter in NASCAR history.
News in Brief: 1965 NASCAR Boycott
The 1964 introduction of the 426 Hemi engine reshaped NASCAR, giving Richard Petty and Chrysler a powerful edge. When NASCAR banned the engine for 1965, Petty and top teams chose to boycott the season, refusing to compete without the Hemi. During the boycott, Petty shifted to drag racing but faced tragedy and legal challenges. A mid-year compromise allowed the Hemi’s return, and Petty quickly reclaimed success on the track. This chapter highlights resilience, loyalty, and the complex balance between innovation and regulation in motorsports.
