The S E F A C(Societa Esercizio Fabbriche Automobili e Corse) was born may 23 rd 1960. Created and administered by Enzo Ferrari and Michel Paul Cavallier, an important french industrialist well known for is passion of cars and racing mechanics. Regularity every three months Michel Paul Cavallier go to Maranello to discuss and set up new project with Enzo Ferrari and is engineers including among those projects.

• Project of the first prototype 250 GT/B s/n 05161 on a chassis and powertrain of the 250 GT, the aluminum body will be studied in a wind tunnel and will become the first 275 GT/B prototype delivered march 20 th 1963.
  The rear had a real affinity with the 250 Lusso and the 250 LM s/n 05149 (they are 5 cars apart) as well as the 1964 GTO 's who will come out a year later.
  In the spring 1963 ,during some test at Fiorano #05161 will roll. It will be acquired by Michel Paul-Cavallier .
  Later made into a cabriolet it will spend some of its life in California in the Sacramento area. In the nineties it will come back to Europe to finally be restored to its original condition.

• Project to built four 275GTB speciales competition  s/n 06701 – 06885 – 07185 - 08249 with much less weight and  higher speed. they were called “speciales competition” quote, unquote, because the CS I and the F I A rules did not admit cars with less than 5% weight or more than 5% power than regular cars. This represented a big challenge due to the constantly changing  rules in this era.

However this four 275GTB specials were built originally for racing by the Ferrari Scuderia. They are in the continuity of the  250 GTO of 1964 all a little different from each other s/n 08249 the only one with the 1966 upgrade (long nose). They all have in common :

• A weight  of 150 to 200kg less

• A very thin aluminium body.

• 250LM type 213 competition motor with ribbed block and four attachments  points .

Shortly after the fourth 275GTB special competition twelve 275GTB/C of the 9000 serie will come out of the factory. Those twelve cars and the four specials will be the only cars equipped with a motor 250 LM competition type 213
