In 1969, Chevelles were offered with an RPO Z25 option called "SS396 Package", available on 2-dr hardtops, 2-dr coupes (sedan), convertibles and the El Caminos. This made the offering in the same structure as the Camaros (RPO Z22 Super Sport package). The RPO Z25 SS396 option included the base 325hp, Turbo-Jet 396 V8, black-accented grille, special hood, ornamentation and suspension, plus sport wheels and F70x14 wide-oval white lettered tires, power disc brakes, and special 3-speed manual transmission. Additional horsepower engines that could be specified when ordering the Z25 SS396 option were the L34 396-350, the L78 396-375, and the L89 396-375 w/aluminum heads. The 2-dr sedan(coupe) was only offered in the 300 Deluxe series that year.
That information is from Chevrolet published sales material and dealership order material from 1969. The 396 engines could not be ordered without the Z25 SS396 option just like in Camaros, so the hood is not optional.
