727 V12 Phantom III chassis were constructed from 1936 to 1939, and many have survived. Although chassis production ceased in 1939 (with one final chassis being built in 1940), cars were still being bodied and delivered in 1940 and 1941. The very last car, though completed in 1941, was not delivered to its owner until 1947.

Engineering

The III is powered by an aluminium-alloy V12 engine of 447in³ (7.32L), having a bore of 3.25 inches (82.5 mm) and a stroke of 4.5 inches (114.3 mm). It is a pushrod engine with overhead valve

s operated by a single camshaft in the valley between the cylinder banks. Early cars had hydraulic tappets or, rather, a unique system of eccentric bushings in each individual rocker that was actuated by a small hydraulic piston; the eccentric bushing ensuring zero valve-lash at the rocker/valve interface. This system was changed to solid adjustable tappets in 1938. The Phantom III is unusual for its twin ignition
