Just an interesting car that is rarely seen, thought I'd put it over here.
Chrysler had a small racing program in the '50s-60s that kept them at the forefront of OEM performance. They took cars to Daytona Beach in Florida for high speed runs and made sure that every year, the new Chrysler 300 was not only the fastest factory stock car in competition, but that each year got faster. This held true for every year but one from '55-61.
The 1961 Daytona Beach cars were a little more specialer than the cars most people bought. The biggest differences were a bigger cam, no choke on the carbs, short runners for the intake, and a first-time manual transmission in a 300, a four-speed. Only 7 to 15 cars were built this way, depends who you ask. The car as delivered went 143mph, which is pretty good for a 4200lb car with all the aerodynamics of a cinder block on skinny tires running on sand.
Andy Granatelli of Paxton superchargers took one of these cars and added two blowers to move it into factory experimental, where the previous record was 153mph. Estimated horsepower for the twin-blown 413 was around 800 and it ran 179.4 mph.
