Need help in determining the IHRA OR NHRA class for a 2013 GS Corvette. Stock except for headers, cam and tune. Weight 3,330 lbs, Tires 13 1/8" wide. Engine HP - 510, at wheel hp 446.

For NHRA you could run STOCK. There are several classes in stock based on the NHRA hp and weight rating. You would have to run a 9 inch tire and you would not be able to use your aftermarket cam. Cam's need to be stock lift only the duration can be changed.
Also for a 2013 Corvette you would need a full cage legal for sub 10.00 et's.
