The L79 cars were not an SS car,many were plain jane hardtop cars like the 300 model, but also came with the Malibu trim. The SS convertibles did have the 13867 code but the SS cars in 68 were only available with a Big Block.
The L79 cars with the Malibu trim had the 13667 code, like this one has.
This is the info from the cowl tag.
