The two camshafts were driven by a complex set of 16 gears from the front of the crankshaft - a very similar arrangement to that used on the Maori engine which had two OHC per bank of cylinders.

A 4-speed transmission initially drove a back axle with differential with a shaft drive rather than the hazardous chains of other cars.

On 17 April Jean Chassagne lapping at 114 mph won the Brooklands Easter Meeting 13th Lighting Short handicap.

The engine has undergone extensive restoration after suffering severe damage in the 1990s and was run for the first time in 20 years in January 2014.

[11][12] During a test fire-up in 1993 to assess the car's condition, disaster struck when a blocked oil way in the engine caused it to seize and "throw a rod".

For several years after that, the car was on display in the museum with a very visible hole in its engine where the piston and connecting rod had exited.

In 2015 the National Motor Museum, Beaulieu launched an appeal to raise funds to build a new gearbox for the Sunbeam 350HP.

The museum's manager and chief engineer, Doug Hill said: During the Sunbeam's long and chequered history, its Achilles heel has been a weak gearbox.

[13] On 21 July 2015 at Pendine beach in Wales the 90th anniversary of Sir Malcolm Campbell's first world land speed record in ‘Bluebird' was recreated by his grandson, Don Wales, also a Land Speed Record holder, who recreated the event in the fully restored car.

This would also require the fabrication of two full length exhaust pipes, a new seat and upholstery, and the re-manufacture of a slightly dropped nose cone and rear wheel spats.
