Ferrari entries only consisted of the factory cars, tuned by SpA SEFAC and there were the private cars of "Scuderia Filipinetti, N.A.R.T., Écurie Francorchamps, Scuderia Picchio Rosso, Gelo Racing Team" and "Escuderia Montjuich" which not receive the same support from the factory. They were considered as field fillers, never as candidate for a win. At Porsche, however, JWA Gulf, KG Salzburg who were then replaced by Martini Racing for the following season, received all direct factory support and the privateers like "AAW Shell Racing" and David Piper Racing received a much better support than Ferrari's clients.
