Yesterday I watches some of the 1970 Daytona 500 on YouTube. I was interested is seeing the Plymouth Super-bird and the Dodge Charger 500 running. That go me thinking, so I decided to look up race speeds from then and now. I found the following to be interesting. 1970 Daytona 500: Pole speed: 194.015 MPH Race average speed 149.601 MPH Race time 3:20:32 2020 Daytona 500: Pole speed 194.582 MPH Race average speed 141.11 MPH Race time 3:42:10 In 50 years a lot has changed but some thing still stay the same.
