The 1955 C-300 sired an entire series of high-performance Chrysler 300 letter cars over the next 11 years, and they are still celebrated today.

In the Motor City, new products are collaborations, by nature and by necessity. Many  people and multiple disciplines are required to bring a car to market. But as much as any single person, the man responsible for the Chrysler C-300 was Bob Rodger. At 37, he was the newly appointed chief engineer of the Chrysler division.

In early August of 1954, Rodger pitched his idea for a high-performance coupe built around the Chrysler FirePower V8, one that could dare to rival the great touring cars of Europe. The hemi V8 had been a sensation from its introduction in 1951, but as yet there was no specific model that was really designed to showcase its capabilities. Chrysler general manager Edwin C. Quinn approved the project, but cautiously. Rodger was granted only a minimal budget.

With no funding available for special tooling or components, Chrysler styling chief Virgil Exner and his staff, including Cliff Voss, Maury Baldwin, and Tom Poirier, mixed and matched existing Chrysler sheet metal pieces to obtain just the right balance of elegance and sport. The body shell was New Yorker; the front clip aka doghouse was borrowed from the Imperial; rear quarter panels and trim were base model Windsor. Exner himself oversaw the final adjustments on the minimalist badging and trim.

Rodger’s combination for the 331 cubic-inch hemi V8 included the “triple nickel” (part number 1556157) cylinder heads, the obvious choice. New for 1955 on the New Yorker, these heads featured wider, free-flowing  ports and larger 1.94-in intake and 1.75-in exhaust valves. The radical solid-lifter camshaft, sporting.440-in intake lift, .435-in lift on the exhaust, and a full 60 degrees of overlap, was originally developed for Briggs  Cunningham’s Le Mans sports racers, it’s said.

With two Carter WCFB four-barrel carburetors and a low-profile batwing air cleaner on top, the C-300 V8 was rated at 300 horsepower at 5,200 RPM and 345 lb-ft of torque at 3,200 RPM—by far the most powerful V8 on the market in 1955. To keep all that muscle manageable on the road, much stiffer 800 lb/in front and 160 lb/in rear springs, special Oriflow shocks, and a fatter front antiroll bar were fitted, with the ride height lowered 1.5 inches. The beefy 12-inch power drum brakes were borrowed from the 5,000-lb Imperial. At just over 4,000 lbs the C-300 was no lightweight itself, but it proved to be remarkably light on its feet.

The first C-300 to rumble off the line at the Jefferson Avenue Chrysler plant was finished in Platinum White, followed by two more in Tango Red. Through the production run of 1,725 cars, just three colors were offered: white, red, and black, while the only available transmission was a PowerFlite two-speed. But from its formal introduction on February 10, 1955, the hemi-fired luxury coupe raised a commotion. “Here is the most powerful sedan in the world,” Tom McCahill declared in Mechanix Illustrated. “This is a hardboiled, magnificent piece of semi-competition, built for the real automotive connoisseur.”

The potential of the C-300 was by no means lost on Carl Kiekhaefer, outboard motor tycoon and operator of the first mega-team in NASCAR. His fleet of professionally prepared C-300s won 27 of 45 races in the series in 1955, 18 of them by Tim Flock, who secured the season championship that year. The performance of the Kiekhaefer team and its mighty Chryslers was so dominating that NASCAR founder Big Bill France feared they would wreck the sport, but that’s another story in itself.
