MM Ferrari 250 GT SWB

The Ultimate Development of the SWB Berlinetta.

Ferrari was determined to win the 1961 International GT Championship for Constructors and produced a handful of very special cars to achieve it. Often referred to as SEFAC Hot Rods or Comp 61s, these cars were lighter and more powerful thanks to the use of several enhancements. These included a special frame using smaller diameter tubing with supplementary bracing to increase rigidity, lightweight body, aluminum bumpers, Plexiglas side windows, raked windscreen, 168B/61 engine fitted with 250 TR cylinder heads using revised cam timing, larger intake ports, six Weber 46 DCF/3 carburetors, and competition exhaust. These cars produced between 285-295 horsepower at 7000 rpm and depending on gear and axle ratios could achieve 160 mph at LeMans. There are generally considered to have been 20 or 21 SEFAC Hot Rods built.

SEFAC is the official abbreviation of Società Esercizio Fabbriche Automobili e Corse; the Ferrari factory in Maranello.
