For what it is worth, the 396/375 Chevelles, Camaros, and Novas were rated by NHRA at 425 horsepower, due to the rating on of the 65 396/425 Corvette. I remember having to weigh more than a 427 Fairlane in my 67 Chevelle. These cars were made obsolete when Chevrolet produced the 1969 427/425 Copo Camaro. I don't remember when the 396 rating was lowered, but Dwight probably has that information.
