The Silver Dawn was produced from 1949 thru 1955, for a total of 761 units. There were 110 produced in 1951. It was the first series built for export only and available only with left-hand steering.
1951 was the first year for the 4,566 cc liter engine. This became known as the 'Big Bore - Small Boot'. The F-head six-cylinder unit had a cast-iron block, aluminum head, seven main bearings, solid valve lifters, a Stromberg carburetor, 6.4:1 compression, and produced approximately 150 horsepower. It was paired with a four-speed column lever-shifted (manual) transmission with a floor shift option available. It had a wheelbase of 120 inches, a length of nearly 200 inches, and weighed around 4,000 lbs.
Coachwork included a factory-bodied four-door saloon and a Park Ward-built drophead coupe.
