The NSCA rules were basicaly the same as those above. Hoodscoop can be up to a 5" opening. I can't tell from these photos how big those hoodscoops are but looks close to 5" to me.
422 motorsports rules arent complient to the rules of a true NSS cars, they are allowing alcohol and modern front suspension for a/fx and ultra cars which disqualifies them from being a true NSS car.thats a different class. looks like they are running a bigger than 10.5 rear slick.
