You know why Nascar uses "1980's technology"? Simple.....less room for cheating. There is a lot of cheating that goes on in Nascar. They use carbeurators because number 1: carbeurators are still king for horsepower and number 2: less room to cheat....they can police that a lot better than they can electronics. Hell, they still use mechanical fuel pumps because you can't cheat with them.
As for the comment about the engines, they make them out of cast iron still because cast iron is strong. It's a race engine and it has to run at full throttle for 4 hours.....it has to be strong.
