Background
The Silver Cloud is a luxury vehicle produced by Rolls-Royce between 1955 and 1966. It served as the flagship Rolls-Royce model during that period and was built to replace the Silver Dawn. It went through three iterations during its production run. The Silver Cloud III was first shown to the public in October of 1962 at the Paris Salon.
Compared to the Silver Cloud II, the Silver Cloud III was able to shed around 220lbs, and gained in power. Specifically, the Silver Cloud III received 2-inch carburetors, one quarter of an inch larger than the carburetors equipped on the Silver Cloud II. This increased the compression ratio to 9:1, reflecting the higher octane levels of premium fuel in major markets, although the lower 8:1 ratio remained as an option.
The engine also received a nitride hardened crankshaft to reflect the extra power being generated, and in response to reports of broken crankshafts in earlier V8 Silver Clouds. External changes were the shift from two headlights to four, and an increased slope of the hood to correspond with the reduced height of the radiator grille.
