[2] The Ferrari 735 LM was converted from the 376 S sports car that contested the Mille Miglia race for the 1955 season.

[4] The 735 LM was developed to compete in the 1955 24 Hours of Le Mans race that Ferrari had won the previous year with the 375 Plus.

After the Le Mans disaster, the new race regulations forced a 2.5-litre cap, so Ferrari returned to the 625-engined Monza models for the 1956 season.

[6] The bore and stroke were 102 by 90 mm (4.0 by 3.5 in) (the same as the Ferrari 735 S’ inline-four engine on which they were based) for a displacement of 4,412.49 cc (4.4 L; 269.3 cu in).

[7] The front suspension was independent with unequal-length wishbones, with coil springs and hydraulic shock absorbers.

Suspension at the rear consisted of a De Dion axle with twin arms and a transverse leaf spring with hydraulic shock absorbers.

[6] The first example of the 735 LM series raced in the 1955 Mille Miglia among smaller capacity 376 S and Monza siblings.

After the seven-hour mark and covering only 76 laps, Maglioli and Hill fell out of the race with an overheating engine and clutch problems.

[12] The race itself remained a black card in the history of motorsport because of the catastrophic crash that occurred, which came to be known as the 1955 Le Mans disaster.

[13] After the failed Le Mans and imposition of the capacity caps for the 1956 season, all four cars ended up in the United States.

[14] In April 1956, during the Del Monte Trophy in Pebble Beach, California, a fatal accident occurred in which Ernie McAfee lost his life.
