The 1973 Medal of Honor Firecracker 400 was a NASCAR Winston Cup Series race that took place on July 4, 1973, at Daytona International Speedway in Daytona Beach, Florida.

This race - and the 1969 and 1971 runnings of this race - was actually called the "Medal of Honor Firecracker 400", in an effort to honor Congressional Medal of Honor winners.^[3]

Race report

This was the first race with new rules regarding carburetor restrictors. It was widely assumed that these rules helped volume production wedge engines, especially that used by Chevrolet.

This race eventually became Marty Robbins' most iconic race during his career in NASCAR. While he would start in 36th place (out of the 40 drivers who made up the racing grid), he would finish the race in eighth place, seven laps down. J.D. McDuffie ended up being the last-place finisher of this race due to an engine problem on lap 2 of 160. It took more than 160 minutes and two caution flags for David Pearson to defeat Richard Petty in front of sixty thousand fans. Six car lengths was the distance between Petty and Pearson. Bobby Allison secured the pole position at 179.619 miles per hour (289.069 km/h) during qualifying.^[2]

The race averaged 158.468 miles per hour (255.030 km/h). Engine problems took numerous other drivers out of the race. All competitors (except for Canadian-born Vic Parsons) were born in the United States. Mercury, Dodge, and Chevrolet made up the majority of the grid. Bobby Allison, Cale Yarborough, Richard Petty and David Pearson were the only lap leaders. The Chevrolet vehicles dominated the race, but after Yarborough and Allison retired it was David Pearson's show.^[2]

Notable crew chiefs in the race were Tim Brew, Jake Elder, Travis Carter, Harry Hyde, Dale Inman, Tom Vandiver, and Bud Moore.^[4]

Vic Parsons scored his best NASCAR finish in seventh place.^[2] Gordon Johncock, fresh from his Indy 500 win, finished 4th at this race.^[2]

The winner of the race won $16,100 ($106,134.48 when considering inflation) while the last-place winner received $1,270 ($8,372.1 when considering inflation). All the prize winnings from this race were $105,080 ($692,708.79 when considering inflation).^[5]
