This Ferrari V12 Colombo engine is said to have been removed from a 1962 Ferrari 250 GTE, and the 3.0-liter Tipo 128/F motor was rebuilt between 2016 and 2017. Work involved overhauling the cylinder heads, replacing the main and rod bearings, balancing the crankshaft, and installing Ross Racing forged pistons along with Ferrea Racing Components valves. The engine retains Ferrari-branded valve covers, intake manifolds, a water pump, a flywheel, and clutch components. Uninstalled equipment includes triple Weber 36 DCS carburetors with individual air cleaners as well as exhaust manifolds, dual distributors, twin Magneti Marelli ignition coils, a mechanical fuel pump, a generator, and a starter. The seller notes that the engine has not been utilized since the rebuild was completed. This Colombo V12 is now offered in California by the seller on behalf of the owner with spare parts and a bill of sale.

The bore of this example was reportedly increased to 73.5mm, at which time Ross Racing forged pistons were installed and the main and connecting rod bearings were replaced. The cylinder heads were overhauled in May 2017 by Cardelli Motorsports of San Mateo, California, and were fitted with Ferrea Racing Components valves along with custom seats and guides. The crankshaft was balanced, the rocker arm bushings were replaced with needle bearings, and a roller link timing chain was also installed.
