The '''1966 Southeastern 500''' was a NASCAR Grand National Series event that was held on March 20, 1966, at Bristol International Speedway in the Bristol, Tennessee.

The transition to purpose-built racecars began in the early 1960s and occurred gradually over that decade. Changes made to the sport by the late 1960s brought an end to the "strictly stock" vehicles of the 1950s.

==Race report== Five hundred laps were done on a paved oval track spanning {{convert|0.500|mi|km}}.<ref name="1966s500"/> The total time of the race was three hours, twenty-four minutes, and twenty-six seconds.<ref name="1966s500"/> There were seven cautions for 92 laps.<ref name="1966s500"/> Speeds were: {{convert|69.952|mi/h|disp=or}} and {{convert|86.248|mi/h|disp=or}} for the pole position speed (accomplished by David Pearson).<ref name="1966s500"/> Dick Hutcherson defeated Paul Lewis by outlapping him more than four times; resulting in Ford's 200th win.<ref name="1966s500"/> The Ray Nichels team had also used the #9 for Larry Frank's entry at Daytona earlier in the season. They also had Don White run multiple car numbers in the 1966 season, so they weren't always consistent with them.

Richard Petty had an injured finger and could not participate in this race; Jim Paschal had to take over as the relief driver.

Twenty-five thousand fans saw thirty-two drivers start a race that only seven would complete.<ref name="1966s500"/> Attrition levels were worse in this Bristol race than it is in the 2010 NASCAR Cup Series season; a rare instance where lower speeds on a track are more dangerous than faster speeds. By contrast, the 2010 Food City 500 would see an average speed of {{convert|79.618|mi/h|disp=or}} and a pole position speed of {{convert|124.63|mi/h|disp=or}} with only eight drivers not being able to complete the race.<ref name="2010fc500">{{cite web | url = http://www.racing-reference.info/race/2010-05/W| title = 2010 Food City 500 - for comparison study| publisher = Racing Reference | accessdate = 2011-01-11}}</ref>

The total winnings for the race were $21,735 in American dollars (${{formatnum:{{Inflation|US|21735|1966|r=0}}}} when inflation is taken into effect).<ref name="1966s500"/> Notable crew chiefs for this race were Bud Hartje, Frankie Scott, Jake Elder, Jack Sullivan and Herman Beam.<ref>{{cite web | url = http://www.racing-reference.info/entrylist/1966-07/W/C| title = 1966 Southeastern 500 crew chief information | publisher = Racing Reference | accessdate = 2018-08-01}}</ref>
