This is a very detailed 3d model of a 1957-61 Ferrari 250TR Colombo 3L engine with gearbox included. The 250 Testa Rossa engine was based on Colombo-designed 3.0L V12 used in 250 GT road and racing cars. Carlo Chiti and other Ferrari engineers made several modifications to increase the performance of this already proven engine. The starting point was a 1953-style cylinder block with an overall capacity of 2953 cc, a 73mm bore and 58.8 mm stroke. Six two-barrel Weber 38 DCN carburetors fed the engine, increased from the 3 carburetors typical for 250 GT engines. The cylinder heads used single overhead cams, 2 valves per cylinder and helical double-coil valve springs (a first for Ferrari). It was mainly used on the Ferrari 250 Testa Rossa cars and also on the Ferrari 625TRC S/N 0680. You can find the last one as a full kit if you click on my username.
