Background
The fledgling Chrysler Corporation quickly became the third best-selling car company in America, gaining an enviable reputation for the performance and quality of its cars – and a key contributor to that reputation was the L-head, seven-main-bearing inline-six.
At 248.9 cubic inches - or 4.1-litres if you like your engine capacity Euro-flavoured - these engines might have been considerably smaller than most of the competition but they punched well above their weight in terms of power and efficiency thanks to lightweight pistons and an optional high compression cylinder head.
This, along with a relatively compact and lightweight body, meant that Chrysler roadsters quickly gained a reputation as some of the fastest cars in their class, something the American firm capitalised on by entering them in some of the most prestigious motorsport events Europe had to offer, including the 1928 Le Mans 24 Hour.
Incredibly, two largely standard, six-cylinder cars took 3rd and 4th positions overall, a result made all the more impressive as they were beaten only by Woolf Barnato in the Bentley 4½ Litre, and Robert Block in the Stuzt Model BB ‘Blackhawk’ - and, lest you think that Chrysler fluked its way to a result, a 70-series took a class win at the Mille Miglia of the same year.
A Series 75 Roadster then finished 6th overall at Le Mans the following year, and took first place in the five-litre class of the 1929 Mille Miglia.
This makes the Chrysler 75 a bona fide motorsport legend, and one that remains competitive even today; still the weapon of choice for many entrants in events like the Peking to Paris Endurance Rally (Vintage Class), it took 1st and 2nd place in 2016, 2nd in 2013, and 3rd in 2010.
But, even legends can be improved, which is exactly what has happened to this 1929 Chrysler 75 Roadster.
