At the end of the racing season 1963/1964 the 250 GTO end their carreers. Ferrari try to replace them with the
250 LM but because of the problems of homologation with the F.I.A., he decide to promote the 275 GTB with the construction of several 275 GTB Speciales competition "officina" called "normales" for the season 1965.
The chassis number of those cars are as follow : #6701 / #6885 / #7185 / #8249
For the season 1966, a speciale #8249, prototype of the 275 GTB/C 9000 serie is built.
These Speciales are all built a little different from each other but all have in common :
- a very thin aluminium body
- a steel and aluminium structure super leight weight
All are equipped with a 250 LM motor type 213/comp. With ribbed block and 4 points of attachments and dry sump like the twelve 275 GTB/C of the 9000 series. (read : FERRARI 275 GTB by Jess G. POURRET).
