This Ferrari Tipo F101AC V12 engine is a rare and historically significant powerplant derived from Ferrari’s legendary Colombo V12 architecture.

The engine was acquired by the seller approximately 15 years ago and has been stored since. Rated by Ferrari at 335 horsepower when new, this naturally aspirated 4.4-liter quad-cam V12 features six Weber carburetors and an aluminum block and heads, delivering the sound, character, and mechanical sophistication for which classic Ferrari V12s are renowned.
