Richard Petty becomes the first repeat winner as he wins the 1966 Daytona 500. The hemi ban that was instituted by NASCAR was lifted late in the 1965 season and Richard Petty was back to his old ways at Daytona. The race was mired with tire trouble as the ever increasing speeds were causing the tires to chunk up due to the heat. For back to back years the race was shortened due to rain with Petty taking the checkered flag on lap 198.

Time of race: 3:04:54
Average Speed: 160.927 mph
Pole Speed: 175.163 mph
Cautions: 4 for 22 laps
Margin of Victory: 1 lap +
Attendance: 90,000
Purse: $28,150

I still have this on video when it originally aired. The first "old race" I ever saw. Back in the early 90's there was no internet to get You Tube or order DVDs of old races. Back then you just got lucky to see old clips during races, and read books
