I"ve seen stockers cross over to super, such as John Calvert with his Mustang. Darcy Clark has a H/SA 340 Duster that will run SS/JA with an intake change. Even given Don Little's vast experience, I'm surprised at that car going all the way to SS/CA. That's what threw me off; my assumption that it would be a better fit in "E." That's a wow, then.
