I barely followed nascar in my life but if actual nascar cars are still sticking to those caveman pushrod 5.8L V8, as far I know, teams used to have fresh engines at each race, unless if a engine was still healthy after a race in poor demanding short ovals like bristol.
Of course is quite unlikely that kind of engine could last 24 hours if set to revving up to >9000rpm all the time as they normally do.
